RX23W Group 28. Realtime Clock (RTCe)
28.2.23 Minute Capture Register n (RMINCPn) (n = 0, 1)/BCNT1 Capture Register n
(BCNT1CPn) (n = 0, 1)
(1) In calendar count mode:
RMINCPn is a read-only register that captures the RMINCNT value when a time capture event is detected.
The event detection times detected by the RTCIC0 and RTCIC1 pins are stored in the RMINCP0 and RMINCP1
registers, respectively.
This register is set to 00h by an RTC software reset.
Before reading from this register, be sure to stop the time capture event detection through the setting of the
RTCCRn.TCCT[1:0] bits.
(2) In binary count mode:
BCNT1CPn is a read-only register that captures the BCNT1 value when a time capture event is detected.
The event detection times detected by the RTCIC0 and RTCIC1 pins are stored in the BCNT1CP0 and BCNT1CP1
registers, respectively.
This register is set to 00h by an RTC software reset.
Before reading from this register, be sure to stop the time capture event detection through the setting of the
RTCCRn.TCCT[1:0] bits.
