PIC32MX FAMILY
REGISTER 21-1:
DS61143A-page 402
bit 5-4
bit 3
bit 2
bit 1
bit 0
Note 1: This register is only reset by Power-on Reset (POR).
Unimplemented: Read as ‘0’
RTCWREN: RTC Value Registers Write Enable bit
1 = RTC Value registers can be written to by the user
0 = RTC Value registers are locked out from being written to by the user
Note: The RTCWREN bit can be set only when the write sequence is enabled. The register can be
RTCSYNC: RTCC Value Registers Read Synchronization bit
1 = RTC Value registers can change while reading due to a roll over ripple that results in an invalid
0 = RTC Value registers can be read without concern about a roll over ripple
HALFSEC: Half-Second Status bit
1 = Second half period of a second
0 = First half period of a second
Note: This bit is read-only. It is cleared to ‘0’ on a write to the SECONDS register.
RTCOE: RTCC Output Enable bit
1 = RTCC clock output enabled – clock presented onto an I/O
0 = RTCC clock output disabled
Note: This bit is ANDed with ON (RTCCON<15>) to produce the effective RTCC output enable.
data read. If the register is read twice and results in the same data, the data can be assumed to
be valid.
RTCCON: RTC CONTROL REGISTER
written to a ‘0’ at any time.
