Legend: — = unimplemented, read as ‘0’. Shaded cells are not used by PWM or Timer2.
Note 1:
Name
2:
The SBOREN bit is only available when the BOREN1:BOREN0 Configuration bits = 01; otherwise, it is
disabled and reads as ‘0’. See Section 4.4 “Brown-out Reset (BOR)”.
These bits are unimplemented on 28-pin devices and read as ‘0’.
