Z8 Encore! XP

The errata listed in

0344 to 0519, where the date code is YYWW (year and week of assembly). Date codes 0442 to 0519 are

mixed; the errata will apply to some units, but not others. These errata are NOT APPLICABLE to date

codes 0520 and later. When reviewing the following errata, it is recommended that you also download the

most recent version of the Product Specification.

Table 1. Z8 Encore! XP F64XX Series Errata Date Code 0344 to 0519

No. Summary

Read protect (RP)

option bit may be

bypassed.

START, STOP and

NAK bits in the I

control register can

be cleared by soft-

ware writing a 0 to

these bits.

Device may not com-

plete Stop Mode

Recovery initiated by

a general-purpose

input/output (GPIO)

pin transition.

are found in Zilog’s Z8 Encore! XP

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:

•

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.
