FWP—Flash Write Protect
RP—Read Protect
0 = User program code is inaccessible. Limited control features are available through the
OCD.
1 = User program code is accessible. All OCD commands are enabled. This setting is the
default for unprogrammed (erased) Flash.
Option bits in this space are altered to change the chip configuration at reset.
Reserved
These Option Bits are reserved for future use and must always be 1. This setting is the
default for unprogrammed (erased) Flash.
MCEN—Motor control enable
0 = Motor control pins are enabled on reset
1 = Normal Pin operation
