areas from/to an AVR target (no support for on-chip debugging).
For the JTAG ICE mkII, both JTAG and ISP mode are supported.
.Pp
The AVR Dragon is supported in JTAG and ISP mode.
(High-voltage programming is not yet supported.)
When used in JTAG mode, the AVR Dragon behaves similar to a
JTAG ICE mkII, so all device-specific comments for that device
will apply as well.
When used in ISP mode, the AVR Dragon behaves similar to an
AVRISP mkII (or JTAG ICE mkII in ISP mode), so all device-specific
comments will apply there.
In particular, the Dragon starts out with a rather fast ISP clock
frequency, so the
.Fl B Ar bitclock
option might be required to achieve a stable ISP communication.
.Pp
The USBasp ISP adapter is also supported, provided
.Nm avrdude
has been compiled with libusb support.
