Chip Errata
DSP56303 Digital Signal Processor
Mask: 4J22A
Motorola SPS 303CE4J22A_2_2 pg. 1 /ng/7/17/00
General remark: In order to prevent the usage of instructions or sequences of instructions
that do not operate correctly, the user is encouraged 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.

ES16
Description (added 10/09/1997):
When the chip is powered up with PLL enabled (PINIT = 1), the skew
between
EXTAL and CLKOUT after the PLL locks cannot be guaranteed at high
frequency (over 50 MHz, not 100% tested).
Workaround:
If skew between EXTAL and CLKOUT is needed, power up with PINIT
= 0, and then enable the PLL by software.
4J22A
ES47
Description (added 10/09/1997):
If the DMA channel and the core access the same 1/4 K internal X data,
Y data, or program memory page, and the DMA interrupt is enabled, a
false interrupt may occur in addition to the correct one.
Workaround:
Ensure that the channel’s DTD status bit in the DSTR is set before
jumping to the Interrupt Service Routine (i.e., the interrupt is correct
only when DTD is set).
Example:
ORG P:I_DMA0
JSSET #M_DTD0,X:M_DSTR,ISR_ ; ISR_ is the Interrupt
Service
; Routine label for DMA
channel 0
