11.8.2
To change the frequency used by the PLL, use the WDT. When changing the frequency only by
switching the divider, do not use the WDT.
1. Before changing the frequency, always clear the TME bit in WTCSR to 0. When the TME bit
2. Set the type of count clock used in the CKS2 to CKS0 bits in WTCSR and the initial values for
3. When the frequency control register (FRQCR) is written, the processor stop temporarily. The
4. When the WDT count overflows, the CPG resumes supplying the clock and the processor
5. The counter stops at the values H'00.
6. Before changing the WTCNT after the execution of the frequency change instruction, always
11.8.3
1. Set the WT/IT bit in WTCSR to 1, set the reset type in the RSTS bit, set the type of count
2. Set the TME bit in WTCSR to 1 to start the count in watchdog timer mode.
3. While operating in watchdog timer mode, rewrite the counter periodically to H'00 to prevent
4. When the counter overflows, the WDT sets the WOVF flag in WTCSR to 1 and generates the
11.8.4
When operating in interval timer mode, interval timer interrupts are generated at every overflow of
the counter. This enables interrupts to be generated at set periods.
1. Clear the WT/IT bit in WTCSR to 0, set the type of count clock in the CKS2 to CKS0 bits, and
2. Set the TME bit in WTCSR to 1 to start the count in interval timer mode.
3. When the counter overflows, the WDT sets the IOVF flag in WTCSR to 1 and an interval
