CHAPTER 6 16-BIT TIMER/EVENT COUNTER 00 (
μPD78F920x ONLY)
User’s Manual U18172EJ3V0UD

Square-wave output operation
Setting
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 6-28 for the set value).
<3>
Set the TOC00 register (see Figure 6-28 for the set value).
<4>
Set any value to the CR000 register (0000H cannot be set).
<5>
Set the TMC00 register to start the operation (see Figure 6-28 for the set value).
Caution
Changing the CR000 setting during TM00 operation may cause a malfunction. To change the
setting, refer to 6.5 Cautions Related to 16-Bit Timer/Event Counter 00 (17) Changing compare
register during timer operation.
Remarks 1. For the setting of the TO00 pin, see 6.3 (5) Port mode register 2 (PM2) and port mode control
register 2 (PMC2).
2. For how to enable the INTTM000 interrupt, see CHAPTER 10 INTERRUPT FUNCTIONS.
A square wave with any selected frequency can be output at intervals determined by the count value preset to 16-
bit timer capture/compare register 000 (CR000).
The TO00 pin output status is reversed at intervals determined by the count value preset to CR000 + 1 by setting
bit 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.
