Description
RAS-CAS Wait Control
These bits select a wait cycle to be inserted between
the RAS assert cycle and CAS assert cycle.
00: Wait cycle not inserted
01: 1-state wait cycle inserted
10: 2-state wait cycle inserted
11: 3-state wait cycle inserted
Description
Status flag that indicates a match between the values of
RTCNT and RTCOR.
[Clearing conditions]
[Setting condition]
When RTCOR = RTCNT
Compare Match Interrupt Enable
Enables or disables interrupt requests (CMI) by the
CMF flag when the CMF flag is set to 1.
This bit is valid when refresh control is not performed
(RFSHE = 0). When the refresh control is performed
(RFSHE = 1), this bit is always cleared to 0 and cannot
be modified.
0: Interrupt request by CMF flag disabled
1: Interrupt request by CMF flag enabled
When 0 is written to CMF after reading CMF = 1
while the RFSHE bit is cleared to 0
When CBR refreshing is executed while the RFSHE
bit is set to 1
