MODE OF OPERATION
The following modes of operation are selectable via jumpers (see section 6. jumper Settings).
3-1.
PARALLEL INTERFACE MODES
In the parallel interface mode, 8-bit instructions and data are sent between the host and the
module 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).
3-1-1.
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.
