CONFIG(0:15)
In
Configuration Register
(0:4) Number Physical DASL Ports - 1 (n-1). (MSB) = Bit 4.
(5:7) Number of Physical Sub-Ports -1 (m-1). MSB = Bit 7. Only two values
are supported:
(5:7)=110
’
for a 16-bit port
(5:7)=111 for a 32-bit port
(8:12) Unique Hardware Version Number (obtain from provider of the source
picocode). MSB = Bit 12.
(13)
External Speed Expansion Mode. This bit should be tied high if external
speed expansion is enabled.
This is a reserved function and should
not be enabled. This bit must be held low.
(14)
Internal Speed Expansion Mode. This bit should be tied high if internal
speed expansion is enabled.
This is a reserved function and should
not be enabled. This bit must be held low
.
(15)
DASL Synchronization Mode: same value as the signal DASLSYNC-
MODE.
Application Port Interface
PORT_ENABLE
In
DASL Port Enable
SYNC_HUNT
In
DASL Synchronization Request
A low to high transition will force the synchronization sequence of the receive
DASL port
PARALLEL_DATA_IN(31:0)
In
Parallel Data In: Data to be transmitted.
TX_SYNCREQ
In
Transmit Link Synchronization Request Input: When active the DASL TXPORT
enters an idle state and will begin the synchronization sequence after the fall-
ing edge.
RX_DATA_IND
Out
Receive Data Indication: indicates, when active, the DATA_OUT bus now
holds valid data
PARALLEL_DATA_OUT(31:0)
Out
Parallel Data Out: data received from the DASL
PORT_ERROR
Out
Port Error: indicates, when active, that an error has been detected by the
Shared DASL Controller.
