(4) TMP0 I/O control register 1 (TP0IOC1)
The TP0IOC1 register is an 8-bit register that controls the valid edge of the capture trigger input signals (TIP00,
TIP01 pins).
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.

Cautions
1.
Rewrite the TP0IS3 to TP0IS0 bits when the
TP0CTL0.TP0CE bit = 0. (The same value can be written
when the TP0CE bit = 1.) If rewriting was mistakenly
performed, clear the TP0CE bit to 0 and then set the bits
again.
2. The TP0IS3 to TP0IS0 bits are valid only in the free-
running timer mode and the pulse width measurement
mode. In all other modes, a capture operation is not
possible.
