IBF: Input Buffer Full Status bit
1
= A word has been received and waiting to be read by the CPU
0
= No word has been received
bit 6
OBF: Output Buffer Full Status bit
1
= The output buffer still holds a previously written word
0
= The output buffer has been read
bit 5
IBOV: Input Buffer Overflow Detect bit (in Microprocessor mode)
1
= A write occurred when a previously input word has not been read
(must be cleared in software)
0
= No overflow occurred
bit 4
PSPMODE: Parallel Slave Port Mode Select bit
1
= Parallel Slave Port mode
0
= General Purpose I/O mode
bit 3
Unimplemented: Read as ‘0’
