CPM97

MCC SS7 - No SUERM interrupt generated after an ABORT

Date Added: 2/25/2003

Description: Octet Count Mode is not entered properly when idles are received after an ABORT.

Therefore N_Cnt is not decremented and no SUERM interrupt will be generated. This problem

only affects the SS7 micro code in ITU-T / ANSI mode (SS7_OPT[STD]=0).

Workaround: Use the latest RAM based SS7 micro code package available from Freescale.

Fix Plan: TBD

2C Erratic behavior can occur if extra clock pulse is detected on SCL

Date Added: 8/25/2003

Description: The I2C controller has an internal counter that counts the number of bits sent. This

counter is reset when the I2C controller detects a START condition. When an extra SCL clock

pulse is inserted in between transactions (before START and after STOP conditions), the internal

counter may not get reset correctly. This could generate partial frames (less than 8 bits) in the next

transaction.

Workaround: Do not generate extra SCL pulses on the I2C bus. In a noisy environment the dig-

ital filter I2MOD[FLT] and additional filtering capacitors should be used on SCL to eliminate

clock spikes that may be misinterpreted as clock pulses.

ABR TCTE[ER-TA] Corruption

Date Added: 8/25/2003

Description: When using the AAL5 ABR ROM microcode it is possible for the TCTE[ER-TA]

field to be overwritten with an erroneous value. This, in turn, will cause the TCTE[ER-BRM] to

be updated with this value. As TCTE[ER-BRM] holds the maximum explicit rate value allowed

for B-RM cells an erroneous value in this field could have a detrimental effect on the network

performance.

Workaround: Use the micro code patch available from Freescale.
