(3) TAAn I/O control register 0 (TAAnIOC0)
The TAAnIOC0 register is an 8-bit register that controls the timer output (TOAAn0, TOAAn1 pins).
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.

Timer output enabled (a square wave is output from the TOAAn1 pin).
Timer output enabled (a square wave is output from the TOAAn0 pin).
Note The output level of the timer output pin (TOAAnm) specified by the
TAAnOLm bit is shown below.
TAAnCE bit
TOAAnm pin output
16-bit counter
• When TAAnOLm bit = 0
TAAnCE bit
TOAAnm pin output
16-bit counter
• When TAAnOLm bit = 1
Cautions 1. Rewrite the TAAnOL1, TAAnOE1, TAAnOL0, and TAAnOE0
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. Even if the TAAnOLm bit is manipulated when the TAAnCE
and TAAnOEm bits are 0, the TOAAnm pin output level
varies.
