Description
Idle Cycle Insertion
An idle cycle can be inserted after a DRAM
read cycle when a continuous normal space
access cycle follows a DRAM read cycle. Idle
cycle insertion conditions, setting of number of
states, etc., comply with settings of bits ICIS1,
ICIS0, and IDLC in BCR register
0: Idle cycle not inserted
1: Idle cycle inserted
Reserved
This bit can be read from or written to.
However, the write value should always be 0.
Precharge State Control
These bits select the number of states in the
RAS precharge cycle in normal access and
refreshing.
00: 1 state
01: 2 states
10: 3 states
11: 4 states
Reserved
These bits 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.
00: Wait cycle not inserted
01: 1-state wait cycle inserted
10: 2-state wait cycle inserted
11: 3-state wait cycle inserted
