CHAPTER 6 16-BIT TIMER/EVENT COUNTERS 00
6.3 Registers Controlling 16-Bit Timer/Event Counter 00
Registers used to control 16-bit timer/event counter 00 are shown below.
• 16-bit timer mode control register 00 (TMC00)
• Capture/compare control register 00 (CRC00)
• 16-bit timer output control register 00 (TOC00)
• Prescaler mode register 00 (PRM00)
• Input switch control register (ISC)
• Port mode register 3 (PM3)
• Port register 3 (P3)
(1) 16-bit timer mode control register 00 (TMC00)
TMC00 is an 8-bit register that sets the 16-bit timer/event counter 00 operation mode, TM00 clear mode, and
output timing, and detects an overflow.
Rewriting TMC00 is prohibited during operation (when TMC003 and TMC002 = other than 00). However, it can
be changed when TMC003 and TMC002 are cleared to 00 (stopping operation) and when OVF00 is cleared to 0.
TMC00 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets TMC00 to 00H.
Caution 16-bit timer/event counter 00 starts operation at the moment TMC002 and TMC003 are set to
values other than 00 (operation stop mode), respectively. Set TMC002 and TMC003 to 00 to
stop the operation.
