• P12/PO10/TIOCC0/TCLKA
The pin function is switched as shown below according to the combination of the TPU channel
0 settings (by bits MD3 to MD0 in TMDR_0, bits IOC3 to IOC0 in TIORL_0, and bits CCLR2
to CCLR0 in TCR_0), bits TPSC2 to TPSC0 in TCR_0 to TCR_5, bit NDER10 in NDERH,
and bit P12DDR.

Pin function TIOCC0 output
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 TCR_0 to TCR_5 is TPSC2 to TPSC0 = B'100.
TCLKA input when phase counting mode is set for channels 1 and 5.
