[Legend]
⎯: Not used as the SSU pin (can be used as an I/O port).
Notes: See tables 20.4 to 20.6.
1. Do not set BIDE to 1 when SSUMS = 1 in SSU.
2. Do not specify that TE = RE = 1 when operating with BIDE = 1 (bidirectional mode).
• P13/PO11/TIOCD0/TCLKB
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 IOD3 to IOD0 in TIORL_0, and bits
CCLR2 to CCLR0 in TCR_0), bits TPSC2 to TPSC0 in TCR_0 to TCR_2, bit NDER11 in
NDERH of PPG, 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 TCR_0 to TCR_2 is TPSC2 to TPSC0 = B'101.
TCLKB input when phase counting mode is set for channels 1 and 5.
