Selection of Pin Functions
The function depends on the counter clear bits 1 and 0 (CCLR1 and CCLR0) in the
timer control register (TCR) of the 8-bit timer, and on the P7
CCLR1, CCLR0: At least one bit is “0.” Both bits are set to “1”

P7
Pin function
This pin always has a general-purpose input/output function, and can simultaneously
be used for external clock input for the 8-bit timer, depending on clock select bits 2 to
0 (CKS2, CKS1, and CKS0) in the timer control register (TCR). See section 11, “8-
bit Timer” for details.
