Bit 7—Compare Match Flag (CMF): Status flag that indicates that the values of RTCNT and
RTCOR match.
Bit 7: CMF
0
1
Note: * Contents do not change when 1 is written to CMF.
Bit 6—Compare Match Interrupt Enable (CMIE): Enables or disables an interrupt request caused
when the CMF bit in RTCSR is set to 1. Do not set this bit to 1 when using CAS-before-RAS
refreshing or auto-refreshing.
Bit 6: CMIE
0
1
Bits 5 to 3—Clock Select Bits (CKS2–CKS0): These bits select the clock input to RTCNT. The
source clock is the external bus clock (CKIO). The RTCNT count clock is CKIO scaled by the
specified ratio.
Bit 5: CKS2

Bit 4: CKS1

Description
The values of RTCNT and RTCOR do not match.
Clearing condition: When a refresh is performed after 0 has been written in
CMF and RFSH = 1 and RMODE = 0 (to perform a CBR refresh).
The values of RTCNT and RTCOR match.
Setting condition: RTCNT = RTCOR*
