60 Refresh Modes (Continued)
62 EXTERNALLY CONTROLLED REFRESH
The user can perform externally controlled refreshes by as-
serting the DISRFSH and RFSH input signals When these
inputs assert the DP844041 will perform a refresh as soon
as possible If the user keeps RFSH asserted with DISRFSH
already asserted the DRAM controller will burst refresh the
memory for as long as the inputs are valid The controller
will guarantee the RAS low and RAS precharge times for
every refresh The user can choose to monitor the output
RFRQ to externally request a refresh When RFRQ asserts
it indicates that the refresh counter has expired
