bit 7 bit 0
Legend:
R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’
-n = Value when device is unprogrammed U = Unchanged from programmed state
bit 7-4 Unimplemented: Read as ‘0’
bit 3-2 BORV<1:0>: Brown-out Reset Voltage bits
11 = Reserved
10 = V
BOR set to 2.7V
01 = V
BOR set to 4.2V
00 = V
BOR set to 4.5V
bit 1 BOREN: Brown-out Reset Enable bit
(1)
1 = Brown-out Reset is enabled
0 = Brown-out Reset is disabled
bit 0 PWRTEN
: Power-up Timer Enable bit
(1)
1 = PWRT is disabled
0 = PWRT is enabled
Note 1: Having BOREN = 1 does not automatically override the PWRTEN to ‘0’, nor automatically enables the
Power-up Timer.
