• P15/TIOCB1/TCLKC
The pin functions are switched as shown below according to the combination of the TPU
channel 1 setting, TPSC2 to TPS0 bits in TCR_0, TCR_2, TCR_4, and TCR_5 and the
P15DDR bit.

Notes: 1. For the setting of the TPU channel, see section 11, 16-Bit Timer Pulse Unit (TPU).
2. This pin functions as TIOCB1 input when TPU channel 1 timer operating mode is set to
normal operating or phase counting mode and IOB3 to IOB0 in TIOR_1 are set to10xx.
3. This pin functions as TCLKC input when TPSC2 to TPSC0 in TCR_0 or TCR_2 are set
to 110 or TPSC2 to TPSC0 in TCR_4 or TCR_0 are 101 or when channels 2 and 4 are
set to phase counting mode.
• P14/TIOCA1/IRQ0
The pin functions are switched as shown below according to the combination of the TPU
channel 1 setting and the P14DDR bit.

Notes: 1. For the setting of the TPU channel, see section 11, 16-Bit Timer Pulse Unit (TPU).
2. This pin functions as TIOCA1 input when TPU channel 1 timer operating mode is set to
normal operating or phase counting mode and IOA3 to IOA0 in TIOR_1 are set to 10xx.
3. When this pin is used as an external interrupt pin, do not specify other functions.
