Description
Idle cycles in CS1 and CS5 space cycles
After read access to the CS1 and CS5 spaces, these bits
insert idle cycles (1) when the write cycle to the CS1
space continues, (2) when the write cycle to the CS5
space continues, or (3) when continuous access is made
to CS spaces except for the CS1 and CS5 spaces.
00: No idle cycle inserted after access to the CS1 and
01: One idle cycle inserted after access to the CS1 and
10: Two idle cycles inserted after access to the CS1 and
11: Three idle cycles inserted after access to the CS1
Idle cycles in CS0 and CS4 space cycles
After read access to the CS0 and CS4 spaces, these bits
insert idle cycles (1) when the write cycle to the CS0
space continues, (2) when the write cycle to the CS4
space continues, or (3) when continuous access is made
to CS spaces except for the CS0 and CS4 spaces.
00: No idle cycle inserted after access to the CS0 and
01: One idle cycle inserted after access to the CS0 and
