IWE8, V3.4
PXB 4219E, PXB 4220E, PXB 4221E
Memory Structure
0 = Cell delineation finite state machine normal operation
1 = Cell delineation finite state machine forced in hunt state
Only the transition 0 → 1 forces the hunt state. Counter (number
of times SYNC state is left) is not incremented. Ocd_start
interrupt is not generated.
delete_idle_ Delete idle/unassigned cells enable
cells
0 = Disabled
1 = Enabled
x43_de
ATM cell payload descrambling enable
scrambling
0 = Disabled
1 = Enabled
channel_
mode
Channel mode
00 = Inactive mode
01 = Active mode (normal mode)
10 = Standby mode
11 = Active mode (normal mode)
ref_slot
Reference slot indicator
1 = This slot is a reference slot
Note: To allow IWE8 internal initialization, all channels must remain in inactive mode for
at least 250 µs after activation of the port (i.e. setting pcfN[p_rx_act] = 1). During
this time the device connected to the Framer Receive Interface has to be in normal
operation.
6.1.1.2 RAM1: ATM Receive Continuation Slot
Read/write Address 00200_H to 003FF_H
Reset value: Not applicable. RAM must be reset and initialized via SW.
