Z8 In-Circuit Emulator

General Description
ZiLOG's in-circuit emulators are interactive, Windows-oriented development tools,
providing a real-time environment for emulation and debugging.
The Z86L99 emulator (Z86L990100ZEM) is a member of ZiLOG's ICEBOXª
product family of in-circuit emulators. The emulator provides essential timing and
I/O circuitry to simplify user emulation of prototype hardware and software
products.
The Z86L99 emulator provides users with a hardware platform to develop and
debug software in a real-time environment. In contrast, software simulators are
significantly slower making them less practical for code development.
The Z86L99 emulator can be connected to any serial port (COM1, COM2, COM3,
and COM4) on the host computer. ZiLOG Developer Studio (ZDS) software
initiates the interaction between the host computer and the emulator.
Notes/Limitations
P43 has a fixed current out. A lengthy cable introduces inductance and can cause
voltage spikes. A long cable can also affect the Analog to Digital Converter (ADC)
accuracy.
In the OTP version, P52 and P53 are EPROM high voltage pins. This means that
these pins do not have pull-up resistance like mask MCU pins.
Note: The mask option pull-up resistance at 3V is approximately
200 KΩ ± 50% at room temperature. Lower voltage can cause
increased resistance.
All registers are read/write (R/W) except

read only
IPR
