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.

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.
