Pin function
According to the operating mode and the setting of the P94DDR bit, the pin function is
switched as shown below.
According to the operating mode and the setting of the P93DDR bit, the pin function is
switched as shown below.
When the TIOCB2/TCLKDS bit in PTCNT2 is set to 1, this pin can be used as the
ExTIOCB2/ExTCLKD2 pin.
According to operating modes, the TPU channel 2 settings by the CS1E bit, the MD3 to MD0
bits in TMDR_2, the IOB3 to IOB0 bits in TIOR_2, and the CCLR1 and CCLR0 bits in
TCR_2, and the combination of the TPSC2 to TPSC0 bits in TCR_0, the TIOCB2/TCLKDS
bit, and the P92DDR bit, the pin function is switched as shown below.
