Operating Example
The above applies under the following conditions:
• Bits BFC and BFD in the TRCMR register are set to 0 (registers TRCGRC and TRCGRD do not operate as buffers).
• Bits EB, EC, and ED in the TRCOER register are set to 0 (output from TRCIOB, TRCIOC, and TRCIOD enabled).
• Bits TOB and TOC in the TRCCR1 register are set to 0 (inactive level), the TOD bit is set to 1 (active level).
• The POLB bit in the TRCCR2 register is set to 1 (“H” active), bits POLC and POLD are set to 0 (“L” active).
