Figure 40 depicts the setup and hold requirements of the trace data pins with respect to TRACECLK, and
Table 38 lists the timing parameters.

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 Figure 40.

FIR Electrical Specifications
FIR implements asynchronous infrared protocols (FIR, MIR) that are defined by IrDA
(Infrared Data
Association). Refer to http://www.IrDA.org for details on FIR and MIR protocols.

Program time for eFuse1
1 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 s)
