PRECAUTION LIST

1.

All Z8 control registers are write only unless stated

otherwise.

2.

Power Supply ramp-up/rise time must be such that

when minimum power-on reset time (T

expires,

then the V

CC

must be in the supported specified

operating range of the device.

3.

Check the T

T

WDT

specifications of the device

that you wish to emulate. The actual specification may

differ from the ICE chip specifications.

4.

The general-purpose registers after Power-On Reset

or at initial emulator use will be different than the actual

device. The emulator self test will always leave the

same values in the general-purpose registers, while

the real device will have a random/undefined value in

the general-purpose registers.

5.

The Emulator cannot be operated while performing

ESD/EMI testing on the target board.

6 .

GUI software versions prior to 3.00 are incompatible

with hardware containing BOOTROM 3.00. The GUI

software may still boot, but will fail at some later point

of the session.

7 .

The status color bar in OTP dialog box will be cleared

in the area where a new window opens on top of it.

8 .

For 386 PCs, set the baud rate to 19.2K or less

because Windows’ communication driver does not

guarantee “reliable” operation at more than 9600

baud. Selecting a high baud rate on some slower 386

machines may crash the Windows environment.

9.

If DSP programs and Z8 programs are to be executed

concurrently, the DSP program must be started first,

then the Z8 program.
