Wakeup Source
Conditions
External Interrupt 0 or 1
The corresponding interrupt must be enabled.
Keyboard Interrupt
The keyboard interrupt feature must be enabled and properly set up. The corresponding interrupt must be
enabled.
Comparator 1 or 2
The comparator(s) must be enabled and properly set up. The corresponding interrupt must be enabled.
Watchdog Timer Reset
The watchdog timer must be enabled via the WDTE bit in the UCFG1 EPROM configuration byte.
Watchdog Timer Interrupt
The WDTE bit in the UCFG1 EPROM configuration byte must not be set. The corresponding interrupt must
be enabled.
Brownout Detect Reset
The BOD bit in AUXR1 must not be set (brownout detect not disabled). The BOI bit in AUXR1 must not be
set (brownout interrupt disabled).
Brownout Detect Interrupt
The BOD bit in AUXR1 must not be set (brownout detect not disabled). The BOI bit in AUXR1 must be set
(brownout interrupt enabled). The corresponding interrupt must be enabled.
Reset Input
