Setting 16-bit timer mode control register 00 (TMC00) and capture/compare control register 00 (CRC00) as shown
The basic operation setting procedure is as follows.
<1> Set the CRC00 register (see Figure 6-11 for the set value).
<2> Set any value to the CR000 register.
<3> Set the count clock by using the PRM00 register.
<4> Set the TMC00 register to start the operation (see Figure 6-11 for the set value).
Caution Changing the CR000 setting during TM00 operation may cause a malfunction. To change the
Remark For how to enable the INTTM000 interrupt, see CHAPTER 10 INTERRUPT FUNCTIONS.
Interrupt requests are generated repeatedly using the count value set in 16-bit timer capture/compare register 000
When the count value of 16-bit timer counter 00 (TM00) matches the value set to CR000, counting continues with
The count clock of the 16-bit timer/event counter can be selected using bits 0 and 1 (PRM000, PRM001) of
