RX23W Group 28. Realtime Clock (RTCe)
28.2.24 Hour Capture Register n (RHRCPn) (n = 0, 1)/BCNT2 Capture Register n
(BCNT2CPn) (n = 0, 1)
(1) In calendar count mode:
RHRCPn is a read-only register that captures the RHRCNT value when a time capture event is detected.
The event detection times detected by the RTCIC0 and RTCIC1 pins are stored in the RHRCP0 and RHRCP1 registers,
respectively.
The PM bit is only enabled when the RCR2.HR24 bit is 0 (in 12-hour mode).
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:
BCNT2CPn is a read-only register that captures the BCNT2 value when a time capture event is detected.
The event detection times detected by the RTCIC0 and RTCIC1 pins are stored in the BCNT2CP0 and BCNT2CP1
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.
