BOREN⁽¹⁾ PWRTEN⁽¹⁾
bit 7
bit 0
Legend:
R = Readable bit
P = Programmable bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
U = Unchanged from programmed state
bit 7-4
bit 3-2
bit 1
bit 0
Unimplemented: Read as ‘0’
BORV1:BORV0: Brown-out Reset Voltage bits
11 = Reserved
10 = VBOR set to 2.7V
01 = VBOR set to 4.2V
00 = VBOR set to 4.5V
BOREN: Brown-out Reset Enable bit⁽¹⁾
1 = Brown-out Reset enabled
0 = Brown-out Reset disabled
PWRTEN: Power-up Timer Enable bit⁽¹⁾
1 = PWRT disabled
0 = PWRT enabled
Note 1: Having BOREN = 1 does not automatically override the PWRTEN to ‘0’ nor automatically enable the
Power-up Timer.
