PARALLEL SLAVE PORT WRITE WAVEFORMS
IBF: Input Buffer Full Status bit
1 = A data byte has been received and is waiting to be read by the CPU
0 = No data byte has been received
OBF: Output Buffer Full Status bit
1 = The output buffer still holds a previously written data byte
0 = The output buffer has been read
IBOV: Input Buffer Overflow Detect bit
1 = A write occurred when a previously input data byte has not been read
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’
