GENERAL DESCRIPTION
Zilog's Z86C02/E02/L02 microcontrollers (MCUs) are
members of the Z8
®
single-chip MCU family, which offer
easy software/hardware system expansion.
For applications demanding powerful I/O capabilities, the
MCU's dedicated input and output lines are grouped into
three ports, and are configurable under software control to
provide timing, status signals, or parallel I/O.
One on-chip counter/timer, with a large number of user-se-
lectable modes, off-load the system of administering real-
time tasks such as counting/timing and I/O data communi-
