GENERAL DESCRIPTION
Allowing easy software development, debug, and prototyp-
ing, ZiLOGÕs new Z8E001 Microcontroller (MCU) offers
a cost-effective One-Time Programmable (OTP) solution to
its single-chip Z8Plus MCU family.
For applications demanding powerful I/O capabilities, the
Z8E001Õs dedicated input and output lines are grouped into
two ports, and are configurable under software control.
Both 8-bit and 16-bit on-chip timers, with a large number
of user-selectable modes, offload the system of administer-
