IBF
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) gets cleared even on byte reading.
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’
IBxF: Input Buffer x Status Full bit
1 = Input buffer contains unread data (reading 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 register (must be cleared in software)
0 = No underflow occurred
Unimplemented: Read as ‘0’
OBxE: Output Buffer x Status Empty bit
1 = Output buffer is empty (writing data to the buffer will clear this bit)
0 = Output buffer contains untransmitted data
