Pin Functions

Port 1 pins also function as the pins for PPG outputs, TPU I/Os*, and DMAC outputs*. The
correspondence between the register specification and the pin functions is shown below.
Note: * Not supported by the H8S/2366.
• P17/PO15*

/TIOCB2/TCLKD
The pin function is switched as shown below according to the combination of the TPU channel
2 settings (by bits MD3 to MD0 in TMDR_2, bits IOB3 to IOB0 in TIOR_2, and bits CCLR1
and CCLR0 in TCR_2), bits TPSC2 to TPSC0 in TCR_0 and TCR_5, bit NDER15*
NDERH, and bit P17DDR.

Notes: *1 Not supported by the H8S/2366.
*2 TIOCB2 input when MD3 to MD0 = B'0000 or B'01xx and IOB3 = 1.
*3 TCLKD input when the setting for either TCR_0 or TCR_5 is TPSC2 to TPSC0 = B'111.
TCLKD input when channels 2 and 4 are set to phase counting mode.
