6.3 Registers Controlling 16-Bit Timer/Event Counters 00 and 01
(1) 16-bit timer mode control register 0n (TMC0n)
150
The following six registers are used to control 16-bit timer/event counters 00 and 01.
• 16-bit timer mode control register 0n (TMC0n)
• Capture/compare control register 0n (CRC0n)
• 16-bit timer output control register 0n (TOC0n)
• Prescaler mode register 0n (PRM0n)
• Port mode register 0 (PM0)
• Port register 0 (P0)
This register sets the 16-bit timer operating mode, the 16-bit timer counter 0n (TM0n) clear mode, and output
timing, and detects an overflow.
TMC0n can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears TMC0n to 00H.
Caution 16-bit timer counter 0n (TM0n) starts operation at the moment TMC0n2 and TMC0n3 are set to

values other than 0, 0 (operation stop mode), respectively. Set TMC0n2 and TMC0n3 to 0, 0 to
stop the operation.
