WDT Wake-up
Brown-out Reset
Interrupt Wake-up from Sleep
Legend: u = unchanged, x = unknown, — = unimplemented bit, reads as ‘0’.
Note 1:
When the wake-up is due to an interrupt and Global Interrupt Enable bit, GIE, is set, the PC is loaded with
the interrupt vector (0004h) after execution of PC + 1.
