Pin Functions and Selection Method
The pin function is switched as shown below according to the combination of the
operating mode, the TPU channel 0 settings (bits MD3 to MD0 in TMDR0, bits IOC3 to
IOC0 in TIOR0L, and bits CCLR2 to CCLR0 in TCR0), bits TPSC2 to TPSC0 in TCR0
to TCR5, bits AE3 to AE0 in PFCR, and bit P12DDR.

Notes: 1. TIOCC0 input when MD3 to MD0 = B'0000 and IOC3 to IOC0 = B'10xx.
2. TCLKA input when the setting for any of TCR0 to TCR5 is: TPSC2 to
TPSC0 = B'100.
Also, TCLKA input when channels 1 and 5 are set to phase counting
mode.
3. Output is disabled for TIOCD0.
When BFA = 1 or BFB = 1 in TMDR0, output is disabled and the settings in
(2) apply.
