The VME master processor writes 07 (hex) to the command byte. Then
the VME master processor writes these parameters to the control status
area of the selected channel:

Parameter: Description:
0207 continuous blockĆtransfer address The module address is the address of the I/O module that is to receive the block
data. It contains the rack (0-15), group (0-7), and slot (0 or 1) numbers of the I/O
module. See Figure 6.17 on page 6Ć43
0209 continuous blockĆtransfer tag The VME master processor writes a number (0-15) that is an index into the
continuous block transfer write table. Only the lower byte is used.
020A continuous blockĆtransfer
status ID
Specifies the VME status ID used when the blockĆtransfer is completed. See
Figure 6.18 on page 6Ć43.
020B continuous blockĆtransfer
interrupt level
Specifies the VME interrupt level used when the blockĆtransfer is completed. See
Figure 6.18 on page 6Ć43.
021F continuous blockĆtransfer
length of data
The VME master processor writes the number of words of continuous
blockĆtransfer data (0-64).
Use the value 0 to let the I/O module determine how many words the scanner can
write. When the blockĆtransfer completes, the 0 is replaced by the actual number
of words written.

READ ONLY configure this parameter at byte offset 0209 (see above)
0303 continuous blockĆtransfer address
READ ONLY configure this parameter at byte offset 0207 (see above)
0305 length of data
READ ONLY configure this parameter at byte offset 021F (see above)
0306 continuous blockĆtransfer
status ID
READ ONLY
configure this parameter at byte offset 020A (see above)
0307 continuous blockĆtransfer
interrupt level
READ ONLY
configure this parameter at byte offset 020B (see above)
0309 continuous blockĆtransfer
scanner flag
Used for Peterson semaphore. See sample code in chapter 8.
030B continuous blockĆtransfer
VME flag
Used for Peterson semaphore. See sample code in chapter 8.
030D continuous blockĆtransfer
turn flag
Used for Peterson semaphore. See sample code in chapter 8.
030F continuous blockĆtransfer
status
READ ONLY
Indicates the status of the continuous blockĆtransfer.
0100 = block transfer disabled
0200 = block transfer pending
0400 = block transfer sent
0800 = block transfer received
0310-0350 continuous blockĆtransfer
write/read data
(64 words)
Contains as many as 64 words of write or read data
