Bit
Initial value
Read/Write
RTMCSR is an 8-bit readable/writable register that selects the refresh timer counter clock. When
the refresh timer is used as an interval timer, RTMCSR also enables or disables interrupt requests.
Bits 7 and 6 of RTMCSR are initialized to 0 by a reset and in the standby modes. Bits 5 to 3 are
initialized to 0 by a reset and in hardware standby mode; they are not initialized in software
standby mode.
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.
