General remark: In order to prevent the use of instructions or sequences of instructions that
do not operate correctly, we encourage you to use the “lint563” program to identify such
cases and use alternative sequences of instructions. This program is available as part of the
Motorola DSP Tools CLAS package.

Some K30A devices shipped under an XC part number are subject to a problem
if operated in DMA mode 5. The problem occurs if two consecutive host
commands are sent to the DSP. The second host command is received, the
corresponding answer message is composed, and the DMA channel is set up
correctly to transmit the message to the host. However, the message is never sent.
The host port status register shows a host transmit data request (bit HTRQ in
HSTR is set.) DTDn is never set, indicating there has been no terminated
transfer. Sequences of: 1. data, 2. host command to terminate the transfer, and
3. acknowledgement from the host work properly and can be repeated as often
as needed. If a second host command is sent to the DSP, without first sending
data, the DMA channel locks up. This problem has proven to be low level to
date, occurring at a rate of about 350 ppm. The product’s performance regarding
this issue does not drift over time; that is, it is not a reliability risk.
The problem can also be manifested in other modes when more than one DMA
channel is operating, with two or more channels moving data while one is
servicing the PCI FIFO. In this case, the channel servicing the PCI FIFO stalls
and the PCI bus enters an endless state of retries.

Description (added 11/24/98):
2K30A
In the Technical Datasheet Voh-TTL should be listed at 2.4 Volts,
not as:
TTL = Vcc-0.4
Workaround:
This is a documentation update.
Description (added 11/24/98):
2K30A
In the Technical Datasheet Iol should be listed as 1.6 mA, not as 3.0
mA.
Workaround:
This is a documentation update.
Description (added 11/24/98):
2K30A
The technical datasheet supplies a maximum value for internal
supply current in Normal, Wait, and Stop modes. These values will
be removed because we will specify only a "Typical" current.
Workaround:
This is a documentation update.
