Description
Reserved
This bit can be read from or written to. However,
the write value should always be 0.
RAS-CAS Wait Control
These bits select a wait cycle to be inserted
between the RAS assert cycle and CAS assert
cycle. A 1- to 4-state wait cycle can be inserted.
00: Wait cycle not inserted
01: 1-state wait cycle inserted
10: 2-state wait cycle inserted
11: 3-state wait cycle inserted
Reserved
These bits can be read from or written to.
However, the write value should always be 0.
Clock Suspend Enable
Enables clock suspend mode for extend read data
during DMAC and EXDMAC single address
transfer with the synchronous DRAM interface.
0: Disables clock suspend mode
1: Enables clock suspend mode
Reserved
This bit can be read from or written to. However,
the write value should always be 0.
Read Data Extension Cycle Number Selection
Selects the number of read data extension cycle
(Tsp) insertion state in clock suspend mode.
These bits are valid when the CKSPE bit is set to
1.
00: Inserts 1 state
01: Inserts 2 state
10: Inserts 3 state
11: Inserts 4 state
