(1) TMQ0 control register 0 (TQ0CTL0)
The TQ0CTL0 register is an 8-bit register that controls the operation of TMQ0.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
The same value can always be written to the TQ0CTL0 register by software.

Cautions 1. Set the TQ0CKS2 to TQ0CKS0 bits when the TQ0CE bit = 0.
When the value of the TQ0CE bit is changed from 0 to 1, the
TQ0CKS2 to TQ0CKS0 bits can be set simultaneously.
2. Be sure to clear bits 3 to 6 to “0”.
