Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-16 Unimplemented: Read as ‘0’
bit 15-0 ALGNERRCNT<15:0>: Alignment Error Count bits
Increment count for frames with alignment errors. Note that an alignment error is a frame that has an FCS
error and the frame length in bits is not an integral multiple of 8 bits (a.k.a., dribble nibble)
Note 1: This register is only used for RX operations.
2: This register is automatically cleared by hardware after a read operation, unless the byte enables for bytes
0/1 are ‘0’.
3: It is recommended to use the SET, CLR, or INV registers to set or clear any bit in this register. Setting or
clearing any bits in this register should be only done for debug/test purposes.
