The above applies under the following conditions:
The CSELi bit in the TRDSTR register is set to 1 (the TRDi register is not stopped by compare match).
Bits BFCi and BFDi in the TRDMR register are set to 0 (registers TRDGRCi and TRDGRDi are not used as buffer registers).
Bits EAi, EBi, and ECi in the TRDOER1 register are set to 0 (enable the TRDIOAi, TRDIOBi and TRDIOCi pin outputs).
Bits CCLR2 to CCLR0 in the TRDCRi register are set to 001b (set the TRDi register to 000h by compare match in the TRDGRAi register).
Bits TOAi and TOBi in the TRDOCR register is set to 0 (initial output “L” to compare match), the TOCi bit is set to 1 (initial output “H” to compare match).
Bits IOA2 to IOA0 in the TRDIORAi register are set to 011b (TRDIOAi output inverted at TRDGRAi register compare match).
Bits IOB2 to IOB0 in the TRDIORAi register are set to 010b (TRDIOBi “H” output at TRDGRBi register compare match).
Bits IOC3 to IOC0 in the TRDIORCi register are set to 1001b (TRDIOCi “L” output at TRDGRCi register compare match).
The IOD3 bit in the TRDIORCi register is set to 1 (TRDGRDi register does not control TRDIOBi pin output).
