IBM Processor for Network Resources
11.8: SEGBF Transmit LCD Size
This register should be loaded with the number of eight-byte words that are needed for the maximum-sized
LCD that will be setup by software. Refer to the previous section describing LCD layout to determine the
number of words required to support the different modes. The minimum value is six. This is the correct value
when running only AAL5 mode; it includes three words of scheduling information, two words shared between
CSKED and SEGBF, and one word for SEGBF to maintain statistics. Setting this register to a value that is too
small will likely cause the chip to function improperly. Setting this register to a value that is too large will
adversely affect performance.
