Communication Processor Module
The first half-word is composed of the following bits:
S—STOP
Bits 1, 4–10—Reserved
These bits are reserved and must be set to 0.
W—Wrap (Final Function Descriptor in Table)
I—Interrupt
OPCODE—Function Operation Code
This field specifies the function to be executed. Table 16-6 contains the value for this field.
16.3.4.8.3 DEMOD Parameter Packet. The DEMOD parameter packet is composed of
seven 16-bit half-words and is described in the table below.
Half-word 1
Half-word 2
Half-word 3
Half-word 4
Half-word 5
Half-word 6
Half-word 7
ADDRESS
0 = Do not stop after executing this function descriptor.
1 = Stop after executing this function descriptor.
0 = This is not the last function descriptor in the function descriptor table.
1 = This is the last function descriptor in the function descriptor table. After this buffer
0 = No interrupt is generated after this function is processed.
1 = A maskable interrupt is generated after this function is processed.
has been used, the CPM processes the first function descriptor that the FDBASE
index pointer points to in the table. The number of function descriptors in this table
are programmable and determined only by the W bit and overall space constraints
of the memory.
