Determining the Cause of a Reset
Upon any Reset, multiple bits in the STATUS and
PCON register are updated to indicate the cause of the
Reset. Table 5-3 and Table 5-4 show the Reset condi-
tions of these registers.

Legend: u = unchanged, x = unknown, - = unimplemented bit, reads as ‘0’.
Note 1: When the wake-up is due to an interrupt and Global Enable bit (GIE) is set, the return address is pushed on
the stack and PC is loaded with the interrupt vector (0004h) after execution of PC + 1.
