7.3 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)
 Port alternate switch control register (MUXSEL)
 Port mode register 0 (PM0)
 Port register 0 (P0)
Note 78K0/IB2 (30 pins) only
(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 clears TMC00 to 00H.
Caution 16-bit timer/event counter 00 starts operation at the moment TMC003 and TMC002 are set to values
other than 00 (operation stop mode), respectively. Set TMC003 and TMC002 to 00 to stop the
operation.
