Parallel Slave Port Status/Control bits:
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 (in Microprocessor mode)
1 = A write occurred when a previously input word 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'
PORTE Data Direction bits:
Bit2: Direction Control bit for pin RE2/CS/AN7
1 = Input
0 = Output
Bit1: Direction Control bit for pin RE1/WR/AN6
1 = Input
0 = Output
Bit0: Direction Control bit for pin RE0/RD/AN5
1 = Input
0 = Output
