IBM Processor for Network Resources
12.8: RXBUF Cell Data Buffer Read/Write Port
Provides read/write access to receive cell data buffer. The array is divided into 16 64-byte buffers used to
buffer/assemble cells received from the line. When this register is read/written, the address provided by
RXBUF Cell Data Buffer Address is used to select the array word to be accessed. RXBUF Cell Data Buffer
Address is auto-incremented on each read/write. Thus, this port can be read/written multiple times to
read/write the entire array.

12.9: RXBUF Cell Info Buffer Address
Provides the read/write address for accessing cell information buffer. This register provides the read/write
address for accessing cell information buffer. When RXBUF Cell Info Buffer Read/Write Port is read/written,
this register is auto-incremented. When the last address is read/written the address rolls over to zero.

12.10: RXBUF Cell Info Buffer Read/Write Port
Provides read/write access to the Receive Cell Info buffer. The array is divided into 16 areas used to provide
information about each received cell from LINKR. When this register is read/written, the address provided by
RXBUF Cell Info Buffer Address is used to select the array word to be accessed. RXBUF Cell Info Buffer
Address is auto-incremented on each read/write. Thus, this port can be read/written multiple times to
read/write the entire array.
