The format of the counter entries is as follows:
int_gen
count_value counter value
6.2.2
Read/write Address 22000
Reset value: Not applicable. RAM must be reset and initialized via SW
Memory size: 4K
Data Sheet
int_gen
If
Reference Slot.auto_reinit_uf = 1B), the re-initialization of the Reassembly Buffer will terminate an underflow
status as soon as start of underflow is detected. Thus, the underflow status for the device is no longer valid
although the underflow condition still exists. No starvation cells due to underflow will be inserted and counter
13 will not increment Therefore, it is recommended to disable “auto-re-initialization on underflow”
(RAM3.AAL Transmit Reference Slot.auto_reinit_uf = 0B) and perform the re-initialization of the reassembly
buffer by software.
