1. User should not write ‘1’s to reserved bits. The value read from a reserved bit is indeterminate.
2. y = 0, 1, 2, 3, 4
3. A 0 disables toggle function. A 1 enables toggle function on CEX[4:0] pin.
4. For PCA WDT mode, also set the WDTE bit in the CMOD register to enable the reset output signal.
1. User should not write ‘1’s to reserved bits. The value read from a reserved bit is indeterminate.
2. y = 0, 1, 2, 3, 4
3. No PCA interrupt is needed to generate the PWM.
4. A 0 disables toggle function. A 1 enables toggle function on CEX[4:0] pin.
5. Enabling an interrupt for the Watchdog Timer would defeat the purpose of the Watchdog Timer.
6. For PCA WDT mode, also set the WDTE bit in the CMOD register to enable the reset output signal.
