DSP56305 Errata  1996 - 2002 Motorola pg. 35 /ng/12/20/02
ED29
Description (added 9/12/1997; identified as a Documentation
errata 2/1/99):
When the ESSI transmits data with the CRA Word Length Control
bits
(WL[2:0]) = 100, the ESSI is designed to duplicate the last bit of the
24-bit transmission eight times to fill the 32-bit shifter. Instead, after
shifting the 24-bit word correctly, eight 0s are being shifted.
Workaround:
None at this time.
Pertains to: UM, Section 7.4.1.7, “CRA Word Length Control.” The
table number is 7-2.

ED30
Description (added 9/12/1997; identified as a Documentation
errata 2/1/99):
When the ESSI transmits data in the On-Demand mode (i.e., MOD
= 1 in CRB and DC[4:0] = $00000 in CRA) with WL[2:0] = 100, the
transmission does not work properly.
Workaround:
To ensure correct operation, do not use the On-Demand mode with
the
WL[2:0] = 100 32-bit Word-Length mode.
Pertains to: UM, Section 7.5.4.1, “Normal/On-Demand Mode
Selection.”
