.It Ar showall
Show all info for the connected part and exit.
Show all info for the connected part, then exit. The -xshow... options
below can be used to assemble a bespoke response consisting of a subset
(or only one item) of all available relevant information about the
connected part and bootloader.
.It Ar showid
Show a unique Urclock ID stored in either flash or EEPROM of the MCU and exit.
Show a unique Urclock ID stored in either flash or EEPROM of the MCU, then 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

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 showdate
Show the last-modified date of the input file for the flash application,
then 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, then exit.
.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 showapp
Show the size of the programmed application and exit.
Show the size of the programmed application, then exit.
.It Ar showstore
Show the size of the unused flash between the application and metadata and exit.
Show the size of the unused flash between the application and metadata, then exit.
.It Ar showmeta
Show the size of the metadata just below the bootloader and exit.
Show the size of the metadata just below the bootloader, then exit.
.It Ar showboot
Show the size of the bootloader and exit.
Show the size of the bootloader, then exit.
.It Ar showversion
Show bootloader version and capabilities, and exit.
Show bootloader version and capabilities, then 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
bootloader for starting the application, then 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 showpart
Show the part for which the bootloader was compiled, then 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
