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

Notes: 1. TIOCB1 input when TPU channel 1 is in normal operation mode
(MD3 to MD0 = B'0000) and input capture is set (IOB3 to IOB0 =
B'10xx).
2. TCLKC input when the setting for either TCR0 or TCR2 is: TPSC2
to TPSC0 = B'110; or when the setting for either TCR4 or TCR5 is
TPSC2 to TPSC0 = B'101.
TCLKC input when channels 2 and 4 are set to phase counting
mode (MD3 to MD0 = B'01xx).
