Pin Selection Method and Pin Functions
P12/TIOCC0/ The pin function is switched as shown below according to the combination of
TCLKA/A22 the operating mode, TPU channel 0 setting (by 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, bit A22E in PFCR1 and bit P12DDR.

2. TIOCC0 input when MD3 to MD0 = B'0000 and IOC3 to IOC0 =
B'10××.
3. TCLKA input when the TCR0 to TCR5 setting is: TPSC2 to TPSC0
= B'100.
TCLKA input when channel 1 and 5 are set to phase counting
mode (MD3 to MD0 = B'01××).
4. TIOCD0 output is disabled.
When BFA = 1 or BFB = 1 in TMDR0, output is disabled and
setting (2) applies.
