Z8F640x Family Devices with Date Codes 0239 and Later, without
QUAL Topmark
The errata listed in
Table 1
are found in Zilog’s Z8F640x family products (includes Z8F480x, Z8F320x,
Z8F240x, and Z8F160x) without a QUAL topmark and with date codes 0239 and later, where the date
code is YYWW (year and week of assembly). When reviewing the following errata, refer to the most
recent version of the product specification. Data contained in this document is Preliminary only.

Summary
The On-Chip
Debugger’s (OCD)
Step, Stuff, and
Execute instructions
do not work if an
interrupt is pending.
Description
The OCD’s Step, Stuff, and Execute instructions do not work if an interrupt is
pending. When in DEBUG mode, the eZ8
TM
CPU will not acknowledge inter-
rupts or DMA requests. However, if an interrupt or DMA request is pending,
the eZ8 CPU will not acknowledge an instruction. If an interrupt is pending and
an OCD Step, Stuff, or Execute instruction is executed, the OCD will wait for-
ever for the eZ8 CPU to acknowledge the opcode because of the pending
interrupt.
Workaround
The OCD must look at the next instruction before single stepping and take
appropriate measures. Instead of executing the Enable Interrupt (EI) instruc-
tion, rewrite the PC to the instruction following the EI and then enable inter-
rupts through a register write to the interrupt control register.
2
Extraneous register There are several instructions during which the CPU performs extra register
reads by the eZ8
reads. Most are addresses the CPU was trying to read, the CPU reads the
CPU.
same register twice. There are a couple instructions where the CPU reads
from random addresses. This is not a problem, unless the register being read
is affected by a read operation. The registers affected by read operations
include the WDTCTL and DMAA_STAT registers and the UART, SPI, and I
2
C
Receive Data registers. If a read occurs on these registers, receive characters
may be lost or the WDT status lost.
Workaround
Do not set RP to %XF.
Also, only use the LDX instruction on peripheral registers affected by read
operations.
3
SPI does not sup-
port single bit data
transfers.
The SPI does not function properly when configured for single-bit data
transfers. This is not a typical SPI data format.
Workaround
None.
