RowPrecharge
Read-write register to program the RAS access
intervals. Note that fields are in bit-reversed order.
RowPrecharge - Set the precharge interval
(Program to 01000)
Byte[1]
RowSense
RowSense - Set the sense interval
(Program to 01100)
Byte[2]
RowImpRestore RowImpRestore - Set the implicit restore interval
(Program to 10010)
Byte[3]
RowExpRestore RowExpRestore - Set the explicit restore interval
(Program to 00100)
MinInterval Register - 7

Byte[3]
SpecFunc
SpecFunc - Performs SetRR burst
refresh and SetPD powerdown entry
MinWriteDelay, MinReadDelay, and MinAckDelay specify the minimum number of cycles allowed between a request
packet and a write data, read data, and acknowledge packet, respectively. SpecFunc is a write-only field that is used
to initiate a SetRR burst refresh or to place the RDRAM into powerdown mode.
