7.4.5
bit timer capture/compare register 00 (CR00).
0 (TOE00) and bit 1 (TOC001) of 16-bit timer output control register 00 (TOC00) to 1. This enables a square wave
with any selected frequency to be output.

The basic operation setting procedure is as follows.
<1> Set the count clock by using the PRM00 register.
<2> Set the CRC00 register (see Figure 7-29 for the set value).
<3> Set the TOC00 register (see Figure 7-29 for the set value).
<4> Set any value to the CR00 register (0000H cannot be set).
<5> Set the TMC00 register to start the operation (see Figure 7-29 for the set value).
Caution CR00 cannot be rewritten during TM00 operation.
Remarks 1. For the setting of the TO00 pin, see 7.3 (5) Port mode register 5 (PM5).
A square wave with any selected frequency can be output at intervals determined by the count value preset to 16-
The TO00 pin output status is reversed at intervals determined by the count value preset to CR00 + 1 by setting bit
