16.3.4.7.2 MOD Function Descriptor. The MOD function descriptor bit table is described
below.
The first word is composed of the following bits:
S—STOP
Bits 1 and 5–10—Reserved
These bits are reserved and must be set to 0.
W—Wrap (Final Function Descriptor in Table)
I—Interrupt
Z— Complex Output
OPCODE—Function Operation Code
This field specifies the function to be executed. Table 16-6 contains the value for this table.
OFFSET + A
OFFSET + C
OFFSET + E
OFFSET + 0
OFFSET + 2
OFFSET + 4
OFFSET + 6
OFFSET + 8
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.
0 = Only the real component of the result is written to the output buffer.
1 = The real and imaginary parts of the result is written to the output buffer.
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.
