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