The above applies under the following conditions:
• Bits BFC and BFD in the TRCMR register are set to 0 (TRCGRC and TRCGRD do not operate as buffers).
• Bits EA, EB, and EC in the TRCOER register are set to 0 (output from TRCIOA, TRCIOB, and TRCIOC enabled).
• The CCLR bit in the TRCCR1 register is set to 1 (set the TRC register to 0000h by TRCGRA compare match).
• In the TRCCR1 register, bits TOA and TOB are set to 0 (“L” initial output until compare match) and the TOC bit is set to 1 (“H” initial output until
• Bits IOA2 to IOA0 in the TRCIOR0 register are set to 011b (TRCIOA output inverted at TRCGRA compare match).
• Bits IOB2 to IOB0 in the TRCIOR0 register are set to 010b (“H” TRCIOB output at TRCGRB compare match).
• Bits IOC2 to IOC2 in the TRCIOR1 register are set to 001b (“L” TRCIOC output at TRCGRC compare match).
• The CSEL bit in the TRCCR2 register is set to 0 (TRC count continues after TRCGRA compare match).
