Description
Idle Cycle Insert 1
Selects whether or not one idle cycle state is to be
inserted between bus cycles when successive external
read cycles are performed in different areas.
0: Idle cycle not inserted in case of successive external
1: Idle cycle inserted in case of successive external read
Idle Cycle Insert 0
Selects whether or not one idle cycle state is to be
inserted between bus cycles when successive external
read and write cycles are performed.
0: Idle cycle not inserted in case of successive external
1: Idle cycle inserted in case of successive external read
Burst ROM enable
Selects whether area 0 is used as a burst ROM
interface.
0: Area 0 is basic bus interface
1: Area 0 is burst ROM interface
Burst Cycle Select 1
Selects the number of burst cycles for the burst ROM
interface.
0: Burst cycle comprises 1 state
1: Burst cycle comprises 2 states
Burst Cycle Select 0
Selects the number of words that can be accessed in a
burst ROM interface burst access.
0: Max. 4 words in burst access
1: Max. 8 words in burst access
Reserved
The write value should always be 0.
