7-1 Parallel Input Interface

In the parallel input interface, the microcomputer controls the LSI via 13 pins of RESET, CMD,

CS, WR, RD and D7-D0.

Command and subcommand data are input from D7-D0 by control of CMD, CS and WR, as

shown in Figure 7-1, and the status is output from D7-D0 by control of RD, as shown in Figure

7-2.
