U-1 U-1 U-1 U-1 R/WO-1 R/WO-1 R/WO-1 R/WO-1

— — — — MSSPMSK1 MSSPMSK2 LS48MHZ IOL1WAY

bit 7 bit 0

Legend: P = Programmable bit WO = Write-Once bit

R = Readable bit W = Writable bit U = Unimplemented bit

-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 MSSPMSK1: MSSP1 7-Bit Address Masking Mode Enable bit

1 = 7-Bit Address Masking mode enable

0 = 5-Bit Address Masking mode enable

bit 2 MSSPMSK2: MSSP2 7-Bit Address Masking Mode Enable bit

1 = 7-Bit Address Masking mode enable

0 = 5-Bit Address Masking mode enable

bit 1 LS48MHZ: Low-Speed USB Clock Selection bit

1 = 48 MHz system clock is expected; divide-by-8 generates low-speed USB clock

0 = 24 MHz system clock is expected; divide-by-4 generates low-speed USB clock

bit 0 IOL1WAY: IOLOCK Bit One-Way Set Enable bit

1 = The IOLOCK bit can only be set once (provided an unlocking sequence is executed); this prevents

any possible future RP register changes

0 = The IOLOCK bit can be set and cleared as needed (provided an unlocking sequence is executed)
