• PB2/A10/TIOCC6/TCLKE
The pin function is switched as shown below according to the combination of the operating
mode, bit EXPE, TPU channel 6 settings (by bits MD3 to MD0 in TMDR_6, bits IOC3 to
IOC0 in TIORL_6, and bits CCLR2 to CCLR0 in TCR_6), bits TPSC2 to TPSC0 in TCR_6 to
TCR_11, and bit PB2DDR.

Notes: 1. TIOCC6 input when MD3 to MD0 = B'0000 and IOC3 to IOC0 = B'10xx.
2. TCLKE input when the setting for any of TCR_6 to TCR_11 is TPSC2 to TPSC0 =
B'100. TCLKE input when phase counting mode is set for channels 7 and 11.
3. TIOCD6 output disabled. Output disabled and settings (2) effective when BFA = 1 or
BFB = 1 in TMDR_6.
