@item -B @var{bitclock}
Specify the bit clock period for the JTAG interface or the ISP clock (JTAG ICE only).
The value is a floating-point number in microseconds.
Alternatively, the value might be suffixed with "Hz", "kHz", or "MHz",
in order to specify the bit clock frequency, rather than a period.
The default value of the JTAG ICE results in about 1 microsecond bit
clock period, suitable for target MCUs running at 4 MHz clock and
above.
