When the corresponding bit in PTCNT2 is set to 1, port A pins can be used as TPU I/O pins
(ExTIOCA1 and ExTIOCC0/ExTCLKA). The relationship between register setting values and pin
functions is as follows.
• PA7/CS3/ExTIOCA1
• Extended Mode (EXPE = 1)
• Single-Chip Mode (EXPE = 0)

When the TIOCA1S bit in PTCNT2 is set to 1, this pin can be used as the ExTIOCA1 pin.
According to operating modes, the TPU channel 1 settings by the CS3E bit in PFCR, the MD3
to MD0 bits in TMDR_1, the IOA3 to IOA0 bits in TIOR_1, and the CCLR1 and CCLR0 bits
in TCR_1, and the combination of the TIOCA1S bit and the PA7DDR bit, the pin function is
switched as shown below.
