Note: Writing a 1 to any field in this register, causes an interrupt to be generated based on the occurrence of that particular event indicated in the corresponding
field in

This register indicates the overflow on a per LID basis from the tributary to main
SPI-4 interface. Bit 0 of register with offset 0x02 indicates overflow for LID 0, bit 3
for LID 3, bit 0 of 2nd register with offset 0x03 indicates overflow for LID 32 and so
on.
Read 1: Indicates overflow for that LID.
Read 0: Indicates no overflow for that LID.
Write 1: Clears the bit.
