bit 0
The Power Control (PCON) register contains flag bit(s), that together with the TO and PD bits,
allows the user to differentiate between the device resets.
Register 5-3: PCON Register
bit 7
MPEEN: Memory Parity Error Circuitry Status bit
This bit reflects the value of the MPEEN configuration bit.
Unimplemented: Read as '0'
PER: Memory Parity Error Reset Status bit
1 = No error occurred
0 = A program memory fetch parity error occurred
POR: Power-on Reset Status bit
1 = No Power-on Reset occurred
0 = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
BOR: Brown-out Reset Status bit
1 = No Brown-out Reset occurred
0 = A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)
Legend
R = Readable bit
U = Unimplemented bit, read as ‘0’
MPEEN
Note 1: BOR is unknown on Power-on Reset. It must then be set by the user and checked
Note 2: It is recommended that the POR bit be cleared after a power-on reset has been
