258 / 818 page ![]() Section 8 I/O Ports Rev.3.00 Mar. 26, 2007 Page 216 of 772 REJ09B0355-0300 8.2.3 Pin Functions Port 1 pins also function as TPU I/O pins (TCLKA, TCLKB, TCLKC, TCLKD, TIOCA0, TIOCB0, TIOCC0, TIOCD0, TIOCA1, TIOCB1, TIOCA2, and TIOCB2), and address output pins (A 23 to A20). Port 1 pin functions are shown in table 8.3. Table 8.3 Port 1 Pin Functions Pin Selection Method and Pin Functions P1 7 /TIOCB2/ TCLKD The pin function is switched as shown below according to the combination of the TPU channel 2 setting (by bits MD3 to MD0 in TMDR2, bits IOB3 to IOB0 in TIOR2, and bits CCLR2 to CCLR0 in TCR2), bits TPSC2 to TPSC0 in TCR0, and bit P17DDR. TPU Channel 2 Setting Table Below (1) Table Below (2) P17DDR — 01 Pin function TIOCB2 output P1 7 input P1 7 output TIOCB2 input* 1 TCLKD input* 2 Notes: 1. TIOCB2 input when input capture is set (IOB3 to IOB0 = B'10xx) in normal operating mode (MD3 to MD0 = B'0000). 2. TCLKD input when the TCR0 setting is: TPSC2 to TPSC0 = B'111. TCLKD input when channel 2 is set to phase counting mode (MD3 to MD0 = B'01xx).
