Note: * Only 0 can be written to clear the flag.
Bit 7—Compare Match Flag (CMF): Status flag that indicates a match between the values of
RTCNT and RTCOR.

1
Bit 6—Compare Match Interrupt Enable (CMIE): Enables or disables the CMI interrupt
requested when the CMF flag is set to 1 in RTMCSR. The CMIE bit is always cleared to 0 when
any of areas 2 to 5 is designated as DRAM space.

Bits 5 to 3—Refresh Counter Clock Select (CKS2 to CKS0): These bits select the clock to be
input to RTCNT from among 7 clocks obtained by dividing the system clock ( ). When the input
clock is selected with bits CKS2 to CKS0, RTCNT begins counting up.
Bit 5

Bits 2 to 0—Reserved: These bits cannot be modified and are always read as 1.
