Section 6 Bus Controller
Bit 3—Compare Match Interrupt Enable (CMIE): Enables or disables interrupt requests (CMI)
by the CMF flag when the CMF flag in DRAMCR is set to 1.
When refresh control is performed (RFSHE = 1), the CMIE bit is always cleared to 0.
Bits 2 to 0—Refresh Counter Clock Select (CKS2 to CKS0): These bits select the clock to be
input to RTCNT from among 7 internal clocks obtained by dividing the system clock ( ). When
the input clock is selected with bits CKS2 to CKS0, RTCNT begins counting up.
