Section 10 I/O Ports
10.10.6 Pin Functions
Port B pins also function as the pins for TPU I/Os and address outputs. The correspondence
between the register specification and the pin functions is shown below.
• PB7/A15/TIOCB8/TCLKH
Legend:
×: Don’t care
Notes: 1. TIOCB8 input when MD3 to MD0 = B'0000 or B'01×× and IOB3 = 1.

Output function
The pin function is switched as shown below according to the combination of the operating
mode, bit EXPE, TPU channel 8 settings (by bits MD3 to MD0 in TMDR_8, bits IOB3 to
IOB0 in TIOR_8, and bits CCLR1 and CCLR0 in TCR_8), bits TPSC2 to TPSC0 in TCR_6
and TCR_11, and bit PB7DDR.
2. TCLKH input when the setting for either TCR_6 or TCR_11 is TPSC2 to TPSC0 =
B'111. TCLKH input when phase counting mode is set for channels 8 and 10.
