(5) TMQ0 I/O control register 2 (TQ0IOC2)
The TQ0IOC2 register is an 8-bit register that controls the valid edge of the external event count input signal
(TIQ00 pin) and external trigger input signal (TIQ00 pin).
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.

Cautions 1. Rewrite the TQ0EES1, TQ0EES0, TQ0ETS1, and TQ0ETS0
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. The TQ0EES1 and TQ0EES0 bits are valid only when the
TQ0CTL1.TQ0EEE bit = 1 or when the external event
count mode (TQ0CTL1.TQ0MD2 to TQ0CTL1.TQ0MD0 bits
= 001) has been set.
3. The TQ0ETS1 and TQ0ETS0 bits are valid only when the
external trigger pulse output mode (TQ0CTL1.TQ0MD2 to
TQ0CTL1.TQ0MD0 bits = 010) or the one-shot pulse
output mode (TQ0CTL1.TQ0MD2 to TQ0CTL1.TQ0MD0 =
011) is set.
