Note 1:
Refer to the “
PIC16F505 Memory Programming Specifications
” (DS41226) to determine how to
access the Configuration Word. The Configuration Word is not user addressable during device
operation.
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = bit is cleared
x = bit is unknown
