Port 0
(P07-P00). Port 0 is an 8-bit, bidirectional, CMOS-
compatible I/O port. These eight I/O lines can be config-
ured under software control as a nibble I/O port, or as an
address port for interfacing external memory. The input
buffers are Schmitt-triggered and nibble programmed. Ei-
ther nibble output that can be globally programmed as
push-pull or open-drain. Low EMI output buffers can be
globally programmed by the software. Port 0 can be placed
under handshake control. In Handshake Mode, Port 3
lines P32 and P35 are used as handshake control lines.
The handshake direction is determined by the configura-
tion (input or output) assigned to Port 0's upper nibble. The
lower nibble must have the same direction as the upper
nibble.
For external memory references, Port 0 provides address
bits A11-A8 (lower nibble) or A15-A8 (lower and upper nib-
ble) depending on the required address space. If the ad-
dress range requires 12 bits or less, the upper nibble of
Port 0 can be programmed independently as I/O while the
lower nibble is used for addressing. If one or both nibbles
are needed for I/O operation, they must be configured by
writing to the Port 0 mode register. In ROMless mode, after
a hardware reset, Port 0 is configured as address lines
A15-A8, and extended timing is set to accommodate slow
memory access. The initialization routine can include re-
configuration to eliminate this extended timing mode. In
ROM mode, Port 0 is defined as input after reset.
Port 0 can be set in the High-Impedance Mode if selected
as an address output state, along with Port 1 and the con-
trol signals /AS, /DS, and R//W (Figure 18).
