Receive ATM Filter # 0, # 1, # 2, # 3 – Filtered Cell Counter – Byte 1 (Address = 0xN74E, 0xN75E,
0xN76E, 0xN77E)
Receive ATM Filter # 0, # 1, # 2, # 3 – Filtered Cell Counter – Byte 0 (Address = 0xN74F, 0xN75F,
0xN76F, 0xN77F)
Each of the four User Cell Filters (within the Receive ATM Cell Processor block) contains their own set of
“Filtered Cell Counter” registers.
The Procedure for Reading Out the Contents of the Receive ATM Filter – Filtered Cell Counter
Register
In order to properly read out the contents of these registers, the user must read these registers in the
following order.
• Receive ATM Filter #0, #1, #2, #3 – Filtered Cell Counter – Byte 3 (Address = 0xN74C, 0xN75C, 0xN76C,
0xN77C)
• Receive ATM Filter #0, #1, #2, #3 – Filtered Cell Counter – Byte 2 (Address = 0xN74D, 0xN75D, 0xN76D,
0xN77D)
• Receive ATM Filter #0, #1, #2, #3 – Filtered Cell Counter – Byte 1 (Address = 0xN74E, 0xN75E, 0xN76E,
0xN77E)
• Receive ATM Filter #0, #1, #2, #3 – Filtered Cell Counter – Byte 0 (Address = 0xN74F, 0xN75F, 0xN76F,
0xN77F)
