PIN FUNCTIONS (Continued)
Z86E30/E31/E40
Z8 4K OTP Microcontroller
Port 1 (P17–P10). Port 1 is an 8-bit, bidirectional, CMOS-
compatible port with multiplexed Address (A7–A0) and
Data (D7–D0) ports. These eight I/O lines can be pro-
grammed as inputs or outputs or can be configured under
software control as an Address/Data port for interfacing
external memory. The input buffers are Schmitt-triggered
and the output buffers can be globally programmed as ei-
ther push-pull or open-drain. Low EMI output buffers can
be globally programmed by the software. Port 1 can be
placed under handshake control. In this configuration, Port
3, lines P33 and P34 are used as the handshake controls

RDY1 and /DAV1 (Ready and Data Available). To inter-
face external memory, Port 1 must be programmed for the
multiplexed Address/Data mode. If more than 256 external
locations are required, Port 0 outputs the additional lines
(Figure 19).
Port 1 can be placed in the high-impedance state along
with Port 0, AS, DS, and R/W, allowing the Z86E40 to
share common resources in multiprocessor and DMA ap-
plications.
