Hi Andy

Unfortunately not. The IR code in the firmware is implemented as a ring
buffer of 50 32bit values. Each consisting of 16bit for high- and 16bit
for lowtime. There is a 'process' checking this ringbuffer and sending
out the IR bits (32bit values) accordingly.

Each IR bit is sent in one of three modes: high-low w/ carrier,
low-high w/ carrier or high-low w/o carrier.

The modes are triggered like this:
high-low w/o carrier (ITT): hightime = 1, lowtime = variable
low-high w/ carrier (RC5): hightime = variable, lowtime = 0
high-low w/ carrier (NEC): hightime != 1, lowtime != 0

So for ITT mode the hightime always needs to be set to one. The
firmware then set the IR Blaster output to high for about 20uS followed
by the lowtime where the output is set low.
