(2) 16-bit timer mode control register (TMC0)
This register sets the 16-bit timer operating mode, the 16-bit timer register clear mode and output timing, and
detects an overflow.
TMC0 is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets TMC0 value to 00H.
Caution The 16-bit timer register starts operation at the moment a value other than 0, 0, 0 (operation
stop mode) is set in TMC01 to TMC03, respectively. Set 0, 0, 0 in TMC01 to TMC03 to stop
the operation.
