Z84C0006FEG

GENERAL
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 thirdgeneration 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 alternate registers accessible to the programmer.
The alternate set allows operation in foreground-background mode or it may be reserved for very fast interrupt response.
