The above applies under the following conditions:
• Bits BFC and BFD in the TRCMR register are set to 0 (registers TRCGRC and TRCGRD are not used as buffer register).
• Bits EA and EB in the TRCOER register are set to 0 (enable TRCIOA and TRCIOB pin outputs).
• The CCLR bit in the TRCCR1 register are set to 1 (set the TRC register to 0000h by compare match in the TRCGRA register).
• Bits TOA and TOB in the TRCCR1 register are set to 0 (initial output “L” to compare match).
• Bits IOA2 to IOA0 in the TRCIOR0 register are set to 011b (TRCIOA output inverted at TRCGRA register compare match).
• Bits IOB2 to IOB0 in the TRCIOR0 register are set to 011b (TRCIOB output inverted at TRCGRB register compare match).
• Bits IOC2 to IOC0 in the TRCIOR1 register are set to 011b (TRCIOA output inverted at TRCGRC register compare match).
• The IOC3 bit in the TRCIOR1 register are set to 0 (TRCIOA output register).
• Bits IOD2 to IOD0 in the TRCIOR1 register are set to 011b (TRCIOB output inverted at TRCGRD register compare match).
• The IOD3 bit in the TRCIOR1 register are set to 0 (TRCIOB output register).
• The CSEL bit in the TRCCR2 register are set to 0 (TRC continues counting after compare match).
