PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
REGISTER 22-1: RCFGCAL: RTCC CALIBRATION AND CONFIGURATION REGISTER⁽¹⁾ (CONTINUED)
bit 7-0
CAL<7:0>: RTC Drift Calibration bits
11111111 = Minimum negative adjustment; subtracts 4 RTC clock pulses every one minute
•

•
10000000 = Maximum negative adjustment; subtracts 512 RTC clock pulses every one minute
01111111 = Maximum positive adjustment; adds 508 RTC clock pulses every one minute

•
00000001 = Minimum positive adjustment; adds 4 RTC clock pulses every one minute
00000000 = No adjustment
Note 1: The RCFGCAL register is only affected by a POR.
2: A write to the RTCEN bit is only allowed when RTCWREN = 1.
3: This bit is read-only. It is cleared to ‘0’ on a write to the lower half of the MINSEC register.
