79 / 112 page  Errata Functional Differences Between MSC8101 (Mask 2K42A) and MSC8103 (Mask 2K87M), Rev. 2 Freescale Semiconductor 79 CPM112 FCC Missing Reset at OverRun Date Added: 12/19/2003 Description: TxBD may not be closed for FCC in Half-duplex 10BaseT Ethernet. There may be a mismatch between the actual transmitted BD and the BD for which status is updated. As a result, the status of one to three BDs may not be updated, and they would appear "Ready", although the associated frames have been transmitted (assuming a frame per BD). Workaround: Use microcode patch provided by Freescale. System Number: 11064, 11067 Fix Plan: N/A 0K40A 1K42A 2K42A 2K87M CPM113 Incorrect Return Value from Event Register Read (SCC, SPI, I2C, and SMC) Date Added: 12/19/2003 Description: When the Event Register is read while the SCC, SPI, I 2C, or SMC is active, it is sometimes read as 0, even though it has some bits set. Workaround: System Number: 11068 Fix Plan: 0K40A 1K42A 2K42A 2K87M CPM115 APC Transmits Unwanted Idle Cells Date Added: 12/19/2003 Description: In heavily loaded ATM applications, if the ATM pace controller (APC) is config- ured for multiple priority levels and a burst of traffic for transmission is sustained long enough on the highest priority APC table, then an unwanted idle cell can be trasmitted on the lower priority APC tables when there are cells available in lower priority APC scheduling table for transmission. The transmission of the unwanted idles could cause the valid ATM cells on lower-priority APC scheduling tables not to be transmitted. This transmission of unwanted idles can affect all ATM channels that are not located in the highest-priority APC scheduling table. Workaround: Increase the size of lower-priority APC scheduling tables so they are large enough to absorb any burst or back-to-back bursts on the highest-priority APC scheduling table. Other- wise, use the microcode patch available from Freescale. System Number: 11069 Fix Plan: 0K40A 1K42A 2K42A 2K87M CPM116 Pointer 93 in Partially Filled (PFM) Mode Date Added: 1/15/2004 Description: In PFM mode, the pointer value of 93 is not generated, causing the loss of synchro- nization at the far end. Also, when the pointer value of 93 is received, the synchronization is lost, which causes a loss of data and the resynchronization routine. Workaround: Use microcode patch provided by Freescale. System Number: 11912 Fix Plan: 0K40A 1K42A 2K42A 2K87M Table 50. 2K87M Errata Errata Number Errata Description Applies to Mask |
