Notes: 1. TIOCC0 input when MD3 to MD0 = B'0000 and IOC3 to IOC0 = B'10xx.
2. TCLKA input when the setting for any of TCR_0 to TCR_5 is TPSC2 to TPSC0 = B'100.
TCLKA input when phase counting mode is set for channels 1 and 5.
3. TIOCD0 output disabled. Output disabled and settings (2) effective when BFA = 1 or
BFB = 1 in TMDR_0.
• P11/DREQ1/PO9/TIOCB0
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 IOB3 to IOB0 in TIORH_0, and bits
CCLR2 to CCLR0 in TCR_0), bit NDER9 in NDERH of PPG, bit USBDRQE in PFCR3 and
bit P11DDR.

Notes: 1. TIOCB0 input when MD3 to MD0 = B'0000 and IOB3 to IOB0 = B'10xx.
2. DREQ1 input when the USBDRQE bit in PFCR3 is 0. Do not set the DREQ1 pin as an
activation source when USBDRQE is 1.
