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 IOD3 to
IOD0 in TIOR0L, and bits CCLR2 to CCLR0 in TCR0), bits TPSC2 to TPSC0 in TCR0
to TCR2, bits AE3 to AE0 in PFCR, and bit P13DDR.

Notes: *1 TIOCD0 input when MD3 to MD0 = B'0000 and IOD3 to IOD0 = B'10xx.
*2 TCLKB input when the setting for any of TCR0 to TCR2 is: TPSC2 to
TPSC0 = B'101.
Also, TCLKB input when channels 1 and 5 are set to phase counting
mode.
