Pin function
Notes: 1. TIOCB1 input when MD3 to MD0 = B'0000 or B'01×× and IOB3 to IOB0 = B'10××.
The pin function is switched as shown below according to the combination of bit SAE1 in
DMABCRH of DMAC, TPU channel 1 settings (by bits MD3 to MD0 in TMDR_1, bits IOB3
to IOB0 in TIOR_1, and bits CCLR1 and CCLR0 in TCR_1), bits TPSC2 to TPSC0 in
TCR_0, TCR_2, TCR_4, and TCR_5, bit NDER13 in NDERH of PPG, bits MSS and BIDE in
SSCRH, bit SSUMS in SSCRL, and bits TE and RE in SSER of SSU, bits SSI0S1 and SSI0S0
in PFCR5, and bit P15DDR.
2. TCLKC input when the setting for either TCR_0 or TCR_2 is TPSC2 to TPSC0 = B'111,
3. SSI0-A input when SSI0S1 and SSI0S0 = B'00 in PFCR5, and SSUMS, BIDE, MSS,
4. SSI0-A output when SSI0S1 and SSI0S0 = B'00 in PFCR5, and SSUMS, BIDE, MSS,
or when the setting for either TCR_4 or TCR_5 is TPSC2 to TPSC0 = B'101. TCLKC
input when phase counting mode is set for channels 2 and 4.
TE, and RE = B'001×1 or B'10××1. Do not set up for TPU output with SSCK0-A input.
TE, and RE = B'0001×.
