1-255: The device number of the targeted GCG Genius Gateway.
0-31: the SBA of the targeted Genius HSC Device from which data is
to be retrieved.
This entry tells the CPU how much memory is being allocated to
store the data returned by the Genius device. The value (in bytes or
bits) depends on the memory type selected as the Deposit Memory
type in Address +10 below.
When a HSC block is configured as a Type A counter, enter 2 for
word memory types or 32 for bit memory types. However, when
configured as a Type B or Type C counter, enter 3 for word memory
types or 48 for bit memory types.
Note that the Read Data Reply Datagram always responds with six
bytes of data. The most significant bytes (Byte 4 & Byte 5) are null.
Bytes 0 thru Byte 3 contain the HSC Data requested.
Enter the code representing the CPU Memory Type where the GCG will
deposit the data obtained from the target Genius Device. Use the
same codes as in Address+2.
Starting address within the Deposit Memory type.
(Byte 4 is msb, Byte 1 is lsb)
