7.6 Transmit Data Structures Descriptions
NOTE:
•
•
•
All ports marked as “Reserved” must be initialized to 0 at initial setup. Software mod-
ifications to these locations after setup will cause incorrect operation.
All read/write port bits marked “Not used” must be written with the value 0 to main-
tain software compatibility with future versions.
All read-only port bits marked “Not used” are driven with a 0 and should be masked
off by the software to maintain compatibility with future versions.
7.6.1 P_FILL_CHAR
Organization: One word
Base address: 4h
Type: Read/Write
Function: Contains the fill character for partially filled cells.
Format: Refer to the following table.
Field (Bits)
Description
Not used
(15:8)
Write with a 0 to maintain future software compatibility.
P_FILL_CHAR
(7:0)
Character used in partially filled cells.
Initialize to the desired value.
7.6.2 T_ADD_QUEUE
Organization: 16 words
Base address: 30h
Index: 2h
Type: Read/Write
Function: Bit table of queues to be added to the calendar queue. To add queues, set the
proper bits in this table to 1. Ensure all other bits in this table are set to 0, then assert
CSD_ATTN in the CMDREG. This table will be scanned in its entirety after the CSD_
ATTN is detected. Bits left asserted from earlier add activities will be added back in
with undesirable results.
Initialization: Initialize to 0.
