Functional Differences Between MSC8101 (Mask 2K42A) and MSC8103 (Mask 2K87M), Rev. 2

CPM35

Data Corruption in SCC Transparent Mode

Date Added: 5/30/2000

Description: When SCC transparent, envelope mode is used and the received frame size is (4*n)

+ 1, the last byte is corrupted. When GSMR_H(RFW) - rx FIFO width is used, the received data

is completely corrupted, not just the last byte.

Workaround: The bug can be worked around with a microcode patch.

System Number: System number; 4350

SI SYNC Timing Restriction

Date Added: 5/30/2000

Description: SI’s sync signal may not change exactly on clock edge in the following cases. The

bug affects operation only when the SI is in one of two modes:

fsd = 00, ce = 0, fe = 0, dsc=1

(Sync sampled with falling edge -> Sync should not change on rising edge)

fsd = 00, ce = 1, fe = 1, dsc=1

(Sync sampled with rising edge -> Sync should not change on falling edge).

Workaround: When working in these modes, the sync signal to the SI should be manipulated

such that it does not change on the exact edge of the serial clock. Toggle the sync at least 5ns after

the edge. One way to implement such a workaround is to add a noninverting buffer between the

device that generates the sync signal and the MSC8101 that uses it.

Heartbeat Error and Carrier Sense Lost Error On Two Frames

Date Added: 5/30/2000

Description: There are rare cases when a heartbeat error and carrier sense lost error are reported

on two frames. The error is reported in the frame in which it occurred, but in those rare cases it is

also reported on an adjacent frame.

Workaround: None

Corruption in AAL0 Cell Payload

Date Added: 5/30/2000

Description: There is a rare case in using the ATM AAL0 transmitter that the AAL0 cell payload

may be corrupted. This can occur in certain internal sequence of events that the user cannot detect

or control.

Workaround:

1. Use the available microcode patch from the web site.

2. When working with AAL0 SAR, place the TCELL_TMP_BASE 64 byte align plus 4. For

example use TCELL_TMB_BASE = 0x2d04 not 0x2d00.
