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
The TMRI function is operative when bits CCLR0 and CCLR1 in the timer control
register (TCR) of the 8-bit timer are both 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.
