Microprocessor Read Section
The microprocessor read uses both read and write
procedures to obtain data from the PDC. A write must be
done to location 5 to select the source of data to be read.
The read source is determined by the value placed on the
lower three bits of C(7:0). The output from a particular read
code is selected using a read address placed on A(2:0). The
output is sent to C(7:0) on the falling edge of RD.
If the Read Address is equal to 111, the Read Code is
ignored, and the status bits shown in Table 22 in the Output
Section is sent to C(7:0). This state was provided so that the
user could obtain the status bits quickly.
Refer to the Timing Diagram in Figure 46. Suppose the input
level detector has a hex value of (321AF5)H, then Table 21
details the steps to be taken.
