Preliminary
11.4: SEGBF Invalid LCD Register
This register provides feedback to the program when the segmentation logic detects an invalid LCD. If multi-
ple invalid LCDs are being processed, this register will contain the address of the last one that was processed
by the segmentation logic. There are several invalid LCD situations that the segmentation logic checks for:
The first is the LCD address not being on the correct boundary. For example, if the chip is configured to have
all LCDs on 128-byte boundaries and an LCD is encountered that is not on a 128-byte boundary. Another
invalid condition is when the transmit length configured in the LCD plus the offset in the LCD when added
together exceed the maximum overall packet size configured in the chip. It is up to the program to determine
which of the possible conditions caused the error to be reported.
