Description
The RP option bit does not prevent Flash access when bypassing the Flash
controller. For more information, refer to Third Party Flash Programming Sup-
port for Z8 Encore!
User code cannot be read through the on-chip debugger when read protect is
enabled. User code can only be read out when bypassing the Flash controller.
Workaround
None
The START, STOP, and NAK bits in the I
software writing a 0 to these bits. The Product Specification states that they
cannot be cleared by writing a 0.
Workaround
None
When Stop Mode Recovery is initiated by a GPIO pin transition, multiple pin
transitions within 200 μs (approximate) of each other may cause the device to
only partially wake up from STOP mode. Therefore, the device idles in a state
between STOP mode and normal operation. The crystal oscillator is oscillat-
ing, but code does not execute.
When stuck in this idle state, assertion of the external RESET pin does not ini-
tiate a system reset.
Workaround
The workarounds are listed below:
Copyright ©2008 by Zilog
Add external filtering to the Stop Mode Recovery pin input signal to pre-
vent multiple transitions in less than 200 μs.
Enable the Watchdog Timer (WDT) in STOP mode to allow a WDT to
complete the Stop Mode Recovery in the event the device does not suc-
cessfully complete the Stop Mode Recovery initiated by the GPIO pin tran-
sition.
