Sample Setup Procedure for PWM Timer Operation (Channels 3 to 5 ): An example of the
setup procedure for PWM timer operation (channels 3 to 5 ) is shown in figure 10.51.
1. Set the first-stage counter clock ' in prescaler register 1 (PSCR1), and select the second-stage
2. Set the port E control register (PECR) or port G control register (PGCR), corresponding to the
3. Set bit T3PWM–T5PWM in the timer mode register (TMDR) to PWM mode. When PWM
4. The GR3A–GR3C, GR4A–GR4C, and GR5A ATU general registers are used as duty registers
5. Set the corresponding bit to 1 in the timer start register (TSTR) to start the free-running
counter clock " with the CKSEL bit in the timer control register (TCR). When selecting an
external clock, at the same time select the external clock edge type with the CKEG bit in TCR.
