Note:
EPROM Protect. EPROM Protect fully protects the Z8 program code from being
read externally. When EPROM Protect is selected, the instructions LDC and LDCI
are supported (Z86E02 SL1925 does not support the instructions LDE and LDEI).
When the device is programmed for ROM Protect, the Low-Noise feature is not
automatically enabled.
Auto Latch Disable. Auto Latch Disable option bit, when programmed, globally
disables all Auto Latches.
Permanent WDT Enable. The hardware-enabled permanent WDT Enable option
bit, when programmed, enables the WDT permanently after exiting reset. Unlike
software-enabled WDT, the hardware-enabled permanent WDT cannot be
stopped even in HALT or STOP modes.
32-KHz Enable. The 32-KHz Enable option bit enables the 32-KHz oscillator cir-
cuit and disables the high-frequency crystal oscillator circuit. This option bit is dis-
abled if the RC oscillator option bit is programmed.
Application Precaution
The production test-mode environment may be enabled accidentally during nor-
mal operation if excessive noise surges above V
In addition, processor operation of Z8
sive noise surges on the P33 (V
the microcontroller is in Standard Mode.
Recommendations for dampening voltage surges in both test and OTP mode
include the following:
•
•
Using a clamping diode to V
Adding a capacitor to the affected pin.
Programming the EPROM/Test Mode Disable option prevents
accidental entry into EPROM Mode or Test Mode.
