Selection Method and Pin Functions

5/TIOCB1/

TCLKC

The pin function is switched as shown below according to the combination of

the TPU channel 1 setting (by bits MD3 to MD0 in TMDR1, bits IOB3 to IOB0

in TIOR1, and bits CCLR2 to CCLR0 in TCR1), bits TPSC2 to TPSC0 in TCR0

and TCR2, and bit P15DDR.

Notes: 1. TIOCB1 input when input capture is set (IOB3 to IOB0 = B'10xx) in

normal operating mode (MD3 to MD0 = B'0000).

2. TCLKC input when either the TCR0 or TCR2 setting is: TPSC2 to

TPSC0 = B'110.

TCLKC input when channel 2 is set to phase counting mode (MD3

to MD0 = B'01xx).
