Second Capture Register n (RSECCPn) (n = 0, 1)/BCNT0 Capture Register n
(BCNT0CPn) (n = 0, 1)
(1) In calendar count mode:
RSECCPn is a read-only register that captures the RSECCNT value when a time capture event is detected.
The event detection times detected by the RTCIC0 and RTCIC1 pins are stored in the RSECCP0 and RSECCP1
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:
BCNT0CPn is a read-only register that captures the BCNT0 value when a time capture event is detected.
The event detection times detected by the RTCIC0 and RTCIC1 pins are stored in the BCNT0CP0 and BCNT0CP1
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.
