IB11 serves as a direct path for transfer
of one spare receiver bit (bit 50) to the
microprocessor.
IB12 and IB13 are used to control the mode
in which the reciever control operates.
Mode 1 provides a 51-bit receiver command
and a 64-bit storage word to the system com-
puter. Mode 2 provides a 51-bit receiver
command and a 51-bit storage word to the sys-
tem computer. Mode 3 provides a 51-bit re-
ceiver command only.

provide paths for data obtained from the
front panel MGC, CLARIFIER, and SWEEP/STEP
RATE controls. CCA A3 converts these analog
(front panel) control inputs into equivalent
binary data. The data are selected by a
unique output port 7 code (see table 5-2,
output port 7), and transferred to the
microprocessor via input port 2:
