Pin Functions and Selection Method
The pin function is switched as shown below according to the combination of the TPU
channel 1 settings (bits MD3 to MD0 in TMDR1, bits IOB3 to IOB0 in TIOR1, and bits
CCLR1 and CCLR0 in TCR1), bits TPSC2 to TPSC0 in TCR0, TCR2, TCR4, and
TCR5, and bit P15DDR.

Notes: 1. TIOCB1 input when MD3 to MD0 = B'0000 or B'01xx and IOB3 to IOB0 =
B'10xx.
2. TCLKC input when the setting for either TCR0 or TCR2 is: TPSC2 to
TPSC0 = B'110, or the setting for either TCR4 or TCR5 is: TPSC2 to
TPSC0 = B'101.
Also, TCLKC input when channels 2 and 4 are set to phase counting
mode.
