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 register).
Bits EAi and EBi in the TRDOER1 register are set to 0 (enable TRDIOAi and TRDIOBi pin outputs).
Bits CCLR2 to CCLR0 in the TRDCRi register are set to 001b (set the TRDi register to 0000h by compare match in the TRDGRAi register).
Bits TOAi and TOBi in the TRDOCR register are set to 0 (initial output “L” 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 011b (TRDIOBi output inverted at TRDGRBi register compare match).
Bits IOC3 to IOC0 in the TRDIORCi register are set to 0011b (TRDIOAi output inverted at TRDGRCi register compare match).
Bits IOD3 to IOD0 in the TRDIORCi register are set to 0011b (TRDIOBi output inverted at TRDGRDi register compare match).
