Z86C8401ZEM
Zilog In-Circuit Emulator-C84
PB006202-0601 3
Additional Items Required (Not Supplied)
A source of power (+4.75 VDC to 5.25 VDC Max[+5.0
VDC typical]) for the emulator. This can be a laboratory
power supply with supply current of 1.5A. A compact
5VDC power supply can be purchased from Zilog using
PN: ZPS05V00ZAC.
Your Target Design: Typically, this is a wire-wrapped or
printed-circuit prototype that includes a socket for the
target device, into which you can plug the emulation
cable from the emulator.
Additional Optional Items (Not Supplied)
25-pin to 9-pin RS-232C Adapter
HP Logic Analyzer Kit (Z89C0000ZHP or
ZINVASM0ZHP)
Software Tools (C Compiler)
Limitations
Permanent WDT Option Bit:
Due to the new Clock Free Reset feature, the Permanent WDT Enable option bit, when programmed, results in invalid
READs when an EXAMINE or READ code is executed. This option should be treated similarly to an EPROM Protect bit.
In essence, do not program the option bit until all else is verified.
Precautions
1. Capacitor C1, at 220 µF, must be removed from the emulator to conduct OTP programming. Please see OTPPROG for
instructions.
2. To set up the jumper pins to emulate the Z86C83 device (see Table 2-2 of the Z86C83 Emulator User’s Manual), the
Port 05 and 06 pod pins must be changed as follows:
• Shunt J4-1 to J5-2, instead of shunting to J4-1 and J4-2
• Shunt J4-2 to J5-1, instead of shunting to J5-1 and J5-2
