Legend:
R = Readable bit
-n = Value at POR
HS = Hardware Set bit
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

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 register occurred (must be cleared in software)
0 = No overflow occurred
Unimplemented: Read as ‘0’
IB3F:IB0F: 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 bits
1 = A read occurred from an empty output byte register (must be cleared in software)
0 = No underflow occurred
Unimplemented: Read as ‘0’
OB3E:OB0E: Output Buffer x Status Empty bit
1 = Output buffer is empty (writing data to the buffer will clear this bit)
0 = Output buffer contains data that has not been transmitted
