PRM00 register,

CRC00 register,

TOC00 register

Note

CR000/CR010 register,

TMC00.TMC001 bit,

port setting

Initial setting of these registers is performed

before setting the TMC003 and TMC002

bits to 01.

Starts count operation

START

<1> Count operation start flow

TMC003, TMC002 bits = 0, 0

The counter is initialized and counting is stopped

by clearing the TMC003 and TMC002 bits to 00.

STOP

<2> Count operation stop flow

Note Care must be exercised when setting TOC00. For details, refer to 7.3 (3) 16-bit timer output control
