Operational Description
Control Word
The data direction and mode of Ports A, B and C are
determined by the contents of the Control Word. See
Figure 11. The Control Word can be both written and read as
shown in Table 1 and 2. During write operations, the function
of the Control Word being written is determined by data bit
D7. If D7 is low, the data on D0 - D3 will set or reset one of
the bits of Port C. See Figure 12. During read Operations,
the Control Word will always be in the format illustrated in
Figure 11 with Bit D7 high to indicate Control Word Mode
Information.
Port C
One 8-bit data output latch/buffer and one 8-bit data input
buffer (no latch for input). This port can be divided into two
4-bit ports under the mode control. Each 4-bit port contains
a 4-bit latch and can be used for the control signal outputs
and status signal inputs in conjunction with Ports A and B.
See Figure 9B.
