GENERAL DESCRIPTION
The Z8400/Z84C00 CPUs are fourth-generation enhanced
microprocessors with exceptional computational power.
They offer higher system throughput and more efficient
memory utilization than comparable second- and third-
generation microprocessors. The speed offerings from 6 -
20 MHz suit a wide range of applications which migrate
software. The internal registers contain 208 bits of read/
write memory that are accessible to the programmer.
These registers include two sets of six general purpose
registers which may be used individually as either 8-bit
registers or as 16-bit register pairs. In addition, there are
two sets of accumulator and flag registers. A group of
“Exchange” instructions makes either set of main or alter-
nate registers accessible to the programmer. The alter-
nate set allows operation in foreground-background mode
or it may be reserved for very fast interrupt response.
The CPU also contains a Stack Pointer, Program Counter,
two index registers, a Refresh register (counter), and an
Interrupt register. The CPU is easy to incorporate into a
system since it requires only a single +5V power source. All
output signals are fully decoded and timed to control
standard memory or peripheral circuits; the CPU is sup-
ported by an extensive family of peripheral controllers.
