Legend:
R = Readable bit WO = Write-Once bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-4 Unimplemented: Program the corresponding Flash Configuration bit to ‘1’
bit 3 Unimplemented: Maintain as ‘0’
bit 2 CP0: Code Protection bit
1 = Program memory is not code-protected
0 = Program memory is code-protected
bit 1-0 Unimplemented: Maintain as ‘1’

Legend:
R = Readable bit WO = Write-Once bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 IESO: Two-Speed Start-up (Internal/External Oscillator Switchover) Control bit
1 = Two-Speed Start-up is enabled
0 = Two-Speed Start-up is disabled
bit 6 FCMEN: Fail-Safe Clock Monitor Enable bit
1 = Fail-Safe Clock Monitor is enabled
