STANDARD NAME:
5.0 MODES OF OPERATION
The following modes of operation are selectable via jumpers (see section 9.0 Jumper Settings).
5.1 PARALLEL INTERFACE MODES
In the parallel interface mode, 8-bit instructions and data are sent between the host and the
modules using either 4-bit nibbles or 8-bit bytes. Nibbles are transmitted high nibble first on
DB4-DB7 (DB0-DB3 are ignored) whereas bytes are transmitted on DB0-DB7. The Register
Select (RS) control signal is used to identify DB0-DB7 as an instruction (low) or data (high).
5.1.1 MOTOROLA M68-TYPE MODE
This mode uses the Read/Write (R/W) and Enable (E) control signals to transfer information.
Instructions/data are written to the module on the falling edge of E when R/W is low and are
read from the module after the rising edge of E when R/W is high.
