bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-2 Unimplemented: Read as ‘0’
bit 1 SPI2OD: SPI2 Open-Drain Output Enable bit
1 = Open-drain capability is enabled
0 = Open-drain capability is disabled
bit 0 SPI1OD: SPI1 Open-Drain Output Enable bit
1 = Open-drain capability is enabled
0 = Open-drain capability is disabled

bit 2-1 RTSECSEL<1:0>: RTCC Seconds Clock Output Select bits
(1)
11 = Reserved; do not use
10 = RTCC source clock is selected for the RTCC pin (can be INTRC, T1OSC or T1CKI, depending
upon the RTCOSC (CONFIG3L<1>) and T1OSCEN (T1CON<3>) bit settings)
01 = RTCC seconds clock is selected for the RTCC pin
00 = RTCC alarm pulse is selected for the RTCC pin
bit 0 PMPTTL: PMP Module TTL Input Buffer Select bit
1 = PMP module uses TTL input buffers
0 = PMP module uses Schmitt Trigger input buffers
Note 1: To enable the actual RTCC output, the RTCOE (RTCCFG<2>) bit needs to be set.
