Unimplemented in 64-pin devices, maintain at ‘1’.
Ensure that the SCLKI pin is made a digital input while using this configuration, see Table 10-1.
Regardless of WPCFG status, if WPEND = 1 or if WPFP corresponds to the Configuration Word’s page,
the Configuration Word’s page is protected.
IOL1WAY: IOLOCK One-Way Set Enable bit
1 = The IOLOCK bit (OSCCON<6>) can be set once, provided the unlock sequence has been
0 = The IOLOCK bit can be set and cleared as needed, provided the unlock sequence has been
Reserved: Always maintain as ‘1’
POSCMD<1:0>: Primary Oscillator Configuration bits
11 = Primary oscillator is disabled
10 = HS Oscillator mode is selected
01 = XT Oscillator mode is selected
00 = EC Oscillator mode is selected
Unimplemented: Read as ‘1’
WPEND: Segment Write Protection End Page Select bit
1 = Protected code segment upper boundary is at the last page of program memory; the lower
0 = Protected code segment lower boundary is at the bottom of the program memory (000000h); upper
WPCFG: Configuration Word Code Page Write Protection Select bit
1 = Last page (at the top of program memory) and Flash Configuration Words are not write-protected
0 = Last page and Flash Configuration Words are write-protected, provided WPDIS = ‘0’
WPDIS: Segment Write Protection Disable bit
1 = Segmented code protection is disabled
0 = Segmented code protection is enabled; protected segment is defined by the WPEND, WPCFG and
ALTPMP: Alternate EPMP Pin Mapping bit
1 = EPMP pins are in default location mode
0 = EPMP pins are in alternate location mode
