Urprotocol is a leaner version of the STK500 1.x protocol that is designed
to be backwards compatible with STK500 v1.x, and allows bootloaders to be
much smaller, eg, as implemented in the urboot project
https://github.com/stefanrueger/urboot. The programmer type ``urclock''
caters for these urboot programmers. Owing to its backward compatibility,
any bootloader that can be served by the arduino programmer can normally
also be served by the urclock programmer.

.It Ar showall
Show all info for the connected part and exit.
.It Ar showid
Show a unique Urclock ID stored in either flash or EEPROM of the MCU and exit.
.It Ar id=<E|F>.<addr>.<len>
Historically, the Urclock ID was a six-byte unique little-endian number
stored in Urclock boards at EEPROM address 257. The location of this
number can be set by the -xid=<E|F>.<addr>.<len> extended parameter. E
stands for EEPROM and F stands for flash. A negative address addr counts
from the end of EEPROM and flash, respectively. The length len of the
Urclock ID can be between 1 and 8 bytes.
.It Ar showapp
Show the size of the programmed application and exit.
.It Ar showstore
Show the size of the unused flash between the application and metadata and exit.
.It Ar showmeta
Show the size of the metadata just below the bootloader and exit.
.It Ar showboot
Show the size of the bootloader and exit.
.It Ar showversion
Show bootloader version and capabilities, and exit.
.It Ar showvbl
Show the vector number and name of the interrupt table vector used by the
bootloader for starting the application, and exit. For hardware-supported
bootloaders this will be vector 0 (Reset), and for vector bootloaders this
will be any other vector number of the interrupt vector table or the slot
just behind the vector table with the name VBL_ADDITIONAL_VECTOR.
.It Ar showdate
Show the last-modified date of the input file for the flash application
and exit. If the input file was stdin, the date will be that of the
programming.
.It Ar showfilename
Show the input filename (or title) of the last flash writing session, and exit.
.It Ar bootsize=<size>
Manual override for bootloader size. Urboot bootloaders put the number of used
bootloader pages into a table at the top of flash, so the urclock programmer can
look up the bootloader size itself. In backward-compatibility mode, when programming
via other bootloaders, this option can be used to tell the programmer the
size, and therefore the location, of the bootloader.
.It Ar vectornum=<arg>
Manual override for vector number. Urboot bootloaders put the vector
number used by a vector bootloader into a table at the top of flash, so
this option is normally not needed for urboot bootloaders. However, it is
useful in backward-compatibility mode (or when the urboot bootloader does
not offer flash read). Specifying a vector number in these circumstances
implies a vector bootloader whilst the default assumption would be a
hardware-supported bootloader.
.It Ar eepromrw
Manual override for asserting EEPROM read/write capability. Not normally
needed for urboot bootloaders, but useful for in backward-compatibility
mode if the bootloader offers EEPROM read/write.
.It Ar emulate_ce
If an urboot bootloader does not offer a chip erase command it will tell
the urclock programmer so during handshake. In this case the urclock
programmer emulates a chip erase, if warranted by user command line
options, by filling the remainder of unused flash below the bootloader
with 0xff. If this option is specified, the urclock programmer will assume
that the bootloader cannot erase the chip itself. The option is useful
for backwards-compatible bootloaders that do not implement chip erase.
.It Ar forcetrim
Upload unchanged flash input files and trim below the bootloader if
needed. This is most useful when one has a backup of the full flash and
wants to play that back onto the device. No metadata are written in this
case and no vector patching happens either if it is a vector bootloader.
However, for vector bootloaders, even under the option -xforcetrim an
input file will not be uploaded for which the reset vector does not point
to the vector bootloader. This is to avoid writing an input file to the
device that would render the vector bootloader not functional as it would
not be reached after reset.
.It Ar initstore
On writing to flash fill the store space between the flash application and
the metadata section with 0xff.
.It Ar title=<string>
When set, <string> will be used in lieu of the input filename. The maximum
string length for the title/filename field is 254 bytes including
terminating nul.
.It Ar nofilename
On writing to flash do not store the application input filename (nor a title).
.It Ar nodate
On writing to flash do not store the application input filename (nor a
title) and no date either.
.It Ar nometadata
On writing to flash do not store any metadata. The full flash below the
bootloader is available for the application. In particular, no data store
frame is programmed.
.It Ar delay=<n>
Add a <n> ms delay after reset. This can be useful if a board takes a
particularly long time to exit from external reset. <n> can be negative,
in which case the default 80 ms delay after issuing reset will be
shortened accordingly.
