EWARN: Error Warning bit

This bit is a flag of the RXWARN and TXWARN bits.

1

 = The RXWARN or the TXWARN bits are set 

0

 = Neither the RXWARN or the TXWARN bits are set 

R = Readable bit

W = Writable bit

C = Clearable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown
