7.4 Interrupt Source
Compare match interrupts (CMI) can be generated when the refresh controller is used as an
interval timer. Compare match interrupt requests are masked/unmasked with the CMIE bit of
RTMCSR.
7.5 Usage Notes
When using the DRAM or pseudo-static RAM refresh function, note the following points:
