Description
This is a 3-bit port for which each bit is configurable as a PAD A
and B input or output. When configured as an input (CPCF = 0),a bit
individually becomes an address (CADLOG = 1 for PSD3X2/3X3,
CATD = 1 for PSD3X1) or a logic input (CADLOG = 0 for
PSD3X2/3X3, CATD = 0 for PSD3X1). The addresses can be
latched with ALE (CADDHLT = 1) or be transparent inputs to the
PADs (CADDHLT = 0). When a pin is configured as an output
(CPCF = 1), it is a function of one product term of all PAD inputs.
See Figure 7.
In multiplexed mode, these pins are the multiplexed low-order
address/data byte. After ALE latches the addresses, these
pins input or output data, depending on the settings of the
RD/E (RD/E/DS on the PSD302/312/303/313), WR/V
PP
or R/W, and
BHE/PSEN pins. In non-multiplexed mode, these pins are the
low-order address input.
In 16-bit multiplexed mode, these pins are the multiplexed
high-order address/data byte. After ALE latches the addresses, these
pins input or output data, depending on the settings of the RD/E or
RD/E/DS, WR/V
PP
or R/W, and BHE/PSEN pins. In all other modes,
these pins are the high-order address input.
