(4) TAAn I/O control register 1 (TAAnIOC1)
The TAAnIOC1 register is an 8-bit register that controls the valid edge of the capture trigger input signals (TIAAn0,
TIAAn1 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 TAAnIS3 to TAAnIS0 bits when the
TAAnCTL0.TAAnCE bit = 0. (The same value can be
written when the TAAnCE bit = 1.) If rewriting was
mistakenly performed, clear the TAAnCE bit to 0 and then
set the bits again.
2. The TAAnIS3 to TAAnIS0 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
performed.
