Description

EBU Configuration Register

Fields

STS

Memory Status Bit

LCKABRT

Lock Abort

SDTRI

SDRAM Tristate

0 (value1): SDRAM control signals are driven by the EBU when the EBU does not own the external bus. SDRAM cannot be shared.

1 (value2): SDRAM control signals are tri-stated by the EBU when the EBU does not own the external bus. The SDRAM can be shared.

EXTLOCK

External Bus Lock Control

0 (value1): External bus is not locked after the EBU gains ownership

1 (value2): External bus is locked after the EBU gains ownership

ARBSYNC

Arbitration Signal Synchronization Control

0 (value1): Arbitration inputs are synchronous

1 (value2): Arbitration inputs are asynchronous

ARBMODE

Arbitration Mode Selection

0 (value1): No Bus arbitration mode selected

1 (value2): Arbiter Mode arbitration mode selected

2 (value3): Participant arbitration mode selected

3 (value4): Sole Master arbitration mode selected

TIMEOUTC

Bus Time-out Control

0 (value1): Time-out is disabled.

1 (value2): Time-out is generated after 1 8 clock cycles.

255 (value3): Time-out is generated after 255 8 clock cycles.

LOCKTIMEOUT

Lock Timeout Counter Preload

GLOBALCS

Global Chip Select Enable

ACCSINH

Access Inhibit request

ACCSINHACK

Access inhibit acknowledge

ALE

ALE Mode

0 (value1): Output is ADV

1 (value2): Output is ALE
