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
PSRAME = 1 or DRAME = 1.
Bits 5 to 3—Clock Select 2 to 0 (CKS2 to CKS0): These bits select an internal clock source for
input to RTCNT. When used for refresh control, the refresh controller outputs a refresh request at
periodic intervals determined by compare match between RTCNT and RTCOR. When used as an
interval timer, the refresh controller generates CMI interrupts at periodic intervals determined by
compare match. These bits are write-disabled when the PSRAME bit or DRAME bit is set to 1.
Bits 2 to 0—Reserved: Read-only bits, always read as 1.
