(1) TMM0 control register (TM0CTL0)
Registers
The TM0CTL0 register is an 8-bit register that controls the operation of TMM0.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
Except for the TM0CE bit, the bits of the TM0CTL0 register cannot be rewritten to different values while TMM0
is operating (bits can be rewritten only to the same value as was previously specified).

After reset: 00H
Cautions 1. Set the TM0CKS2 to TM0CKS0 bits while TMM0 is stopped (TM0CE bit =
Remark
TM0CKS2
When the TM0CE bit is cleared to 0, the internal clock of TMM0 is disabled (fixed to
low level) and 16-bit counter is reset asynchronously.
