Function
PADA and PADB Inputs
In CSI mode (when high), PAD deselects all of its outputs and enters a
power-down mode (see Tables 7A and 7B). In A19 mode, it is another
input to the PAD.
A19/CSI
A16–A18
These are general purpose inputs from Port C. See Figure 4, Note 3.
A11–A15
These are address inputs.
RD/E
This is the read pulse or enable strobe input.
WR or R/W
This is the write pulse or R/W select signal.
ALE/AS
This is the ALE or AS input to the chip.
RESET
This deselects all outputs from the PAD; it can not be used in product
term equations. See Tables 8A and 8B.
PADA Outputs
These are internal chip-selects to the 8 EPROM banks. Each bank can
be located on any boundary that is a function of one product term of the
PAD address inputs.
ES0–ES7
This internal chip-select selects the I/O ports. It can be placed on any
boundary that is a function of one product term of the PAD inputs. See
Table 5.
CSIOPORT
PADB Outputs
CS0–CS3
These chip-select outputs can be routed through Port B. Each of them is
a function of up to four product terms of the PAD inputs.
CS4–CS7
These chip-select outputs can be routed through Port B. Each of them is
a function of up to two product terms of the PAD inputs.
CS8–CS10
These chip-select outputs can be routed through Port C. See Figure 4,
Note 3. Each of them is a function of one product term of the PAD inputs.
