Legend:
R = Readable bit
-n = Value at POR
HS = Hardware Settable bit
W = Writable bit
‘1’ = Bit is set
HSC = Hardware Settable/Clearable bit
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 register occurred (must be cleared in software)
0 = No overflow occurred
Unimplemented: Read as ‘0’
IB3F:IB0F: Input Buffer x Status Full bits⁽¹⁾
1 = Input buffer contains unread data (reading the buffer will clear this bit)
0 = Input buffer does not contain 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 Buffer register (must be cleared in software)
0 = No underflow occurred
Unimplemented: Read as ‘0’
OB3E:OB0E: Output Buffer x Status Empty bits
1 = Output Buffer x is empty (writing data to the buffer will clear this bit)
0 = Output Buffer x contains untransmitted data
Note 1: Even though an individual bit represents the byte in the buffer, the bits corresponding to the word
(Byte 0 and 1 or Byte 2 and 3) get cleared, even on byte reading.
