4.3.10.1 Half-Rate Clocking Mode
When half-rate clocking is used, the trace data signals are sampled by the TPA on both the rising and falling
edges of TRACECLK, where TRACECLK is half the frequency of the clock shown in
4.3.11
FIR implements asynchronous infrared protocols (FIR, MIR) that are defined by IrDA
Association). Refer to http://www.IrDA.org for details on FIR and MIR protocols.

The program length is defined by the value defined in the epm_pgm_length[2:0] bits of the IIM module. The value to program
is based on a 32 kHz clock source (4 * 1/32 kHz = 125 µs).
