Bit
IBF: Input Buffer Full Status bit
1 = All writable input buffer registers are full
0 = Some or all of the writable input buffer registers are empty
IBOV: Input Buffer Overflow Status bit
1 = A write attempt to a full input byte buffer occurred (must be cleared in software)
0 = No overflow occurred
IBxF: Input Buffer x Status Full bits
1 = Input Buffer contains data that has not been read (reading buffer will clear this bit)
0 = Input Buffer does not contain any unread data
OBE: Output Buffer Empty Status bit
1 = All readable output buffer registers are empty
0 = Some or all of the readable output buffer registers are full
OBUF: Output Buffer Underflow Status bit
1 = A read occurred from an empty output byte buffer (must be cleared in software)
0 = No underflow occurred
Unimplemented: Read as ‘0’
OBxE: Output Buffer x Status Empty bits
1 = Output buffer is empty (writing data to the buffer will clear this bit)
0 = Output buffer contains data that has not been transmitted
