IBF: Input Buffer Full Status bit
1 = A word has been received and is waiting to be read by the CPU
0 = No word has been received
OBF: Output Buffer Full Status bit
1 = The output buffer still holds a previously written word
0 = The output buffer has been read
IBOV: Input Buffer Overflow Detect bit
1 = A write occurred when a previously input word had not been read (must be cleared in software)
0 = No overflow occurred
PSPMODE: Parallel Slave Port Mode Select bit
1 = Parallel Slave Port mode
0 = General Purpose I/O mode
Unimplemented: Read as ‘ 0 ’
