(3) TMQ0 I/O control register 0 (TQ0IOC0)
The TQ0IOC0 register is an 8-bit register that controls the timer output (TOQ00 to TOQ03 pins).
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.

TOQ0m pin output setting (m = 0 to 3)
Timer output disabled
• When TQ0OLm bit = 0: Low level is output from the TOQ0m pin
• When TQ0OLm bit = 1: High level is output from the TOQ0m pin
7 <0>
Timer output enabled (a square wave is output from the TOQ0m pin).
Note The output level of the timer output pin (TOQ0m) specified by the
TQ0OLm bit is shown below.
TQ0CE bit
TOQ0m output pin
16-bit counter
• When TQ0OLm bit = 0
TQ0CE bit
TOQ0m output pin
16-bit counter
• When TQ0OLm bit = 1
Cautions 1. Rewrite the TQ0OLm and TQ0OEm bits when the
TQ0CTL0.TQ0CE bit = 0. (The same value can be written
when the TQ0CE bit = 1.) If rewriting was mistakenly
performed, clear the TQ0CE bit to 0 and then set the bits
again.
2. Even if the TQ0OLm bit is manipulated when the TQ0CE and
TQ0OEm bits are 0, the TOQ0m pin output level varies.
