(3) TMPn I/O control register 0 (TPnIOC0)
The TPnIOC0 register is an 8-bit register that controls the timer output (TOPn0, TOPn1 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 TOPn1 pin).
Timer output enabled (a square wave is output from the TOPn0 pin).
Note The output level of the timer output pin (TOPnm) specified by the
TPnOLm bit is shown below (m = 0, 1).

16-bit counter
• When TPnOLm bit = 0
TPnCE bit
TOPnm output pin
16-bit counter
• When TPnOLm bit = 1
Cautions 1. Rewrite the TPnOL1, TPnOE1, TPnOL0, and TPnOE0 bits
when the TPnCTL0.TPnCE bit = 0. (The same value can be
written when the TPnCE bit = 1.) If rewriting was
mistakenly performed, clear the TPnCE bit to 0 and then
set the bits again.
2. Even if the TPnOLm bit is manipulated when the TPnCE
and TPnOEm bits are 0, the TOPnm pin output level varies
(m = 0, 1).
