Unimplemented: Read as ‘1’
LVP: Low-Voltage Programming Enable bit
1 = Low-voltage programming enabled. MCLR/VPP pin function is MCLR. MCLRE Configuration bit
is ignored.
The LVP bit cannot be written (to zero) while operating from the LVP programming interface. The
purpose of this rule is to prevent the user from dropping out of LVP mode while programming
from LVP mode, or accidentally eliminating LVP mode from the Configuration state.
0 = HV on MCLR/VPP must be used for programming
SCANE: Scanner Enable bit
1 = Scanner module is available for use, SCANMD bit enables the module
0 = Scanner module is NOT available for use, SCANMD bit is ignored
Unimplemented: Read as ‘1’
WRTD: Data EEPROM Write Protection bit
1 = Data EEPROM NOT write-protected
0 = Data EEPROM write-protected
WRTB: Boot Block Write Protection bit
1 = Boot Block NOT write-protected
0 = Boot Block write-protected
WRTC: Configuration Register Write Protection bit
1 = Configuration Register NOT write-protected
0 = Configuration Register write-protected
