DESCRIPTION
Receive ATM Cell Processor Block Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Receive ATM Cell Processor block. If the user
wishes to operate a given Channel in the ATM Mode, then he/
she must enable the Receive ATM Cell Processor block.
0 - Disables the Receive ATM Cell Processor block.
1 - Enables the Receive ATM Cell Processor block.
Test Cell Receiver Mode Enable:
This READ/WRITE bit-field permits the user to enable the Test
Cell Receiver (within the Receive ATM Cell Processor block).
The user must implement this configuration option in order to
perform diagnostic operations with Test Cells.
0 - Disables the Test Cell Receiver.
1 - Enables the Test Cell Receiver.
NOTE: For normal operation, the user should set this bit-field to
"1".
