GENERAL DESCRIPTION
The Z86E33/733/E34/E43/743/E44 8-Bit One-Time Pro-
grammable (OTP) Microcontrollers are members of Zilog's
single-chip Z8
circuitry, programmable Watch-Dog Timers, Low Noise
EMI options, and easy hardware/software system expan-
sion capability.
Four basic address spaces support a wide range of mem-
ory configurations. The designer has access to three addi-
