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 (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'
PORTE Data Direction Bits
TRISE2: Direction Control bit for pin RE2/CS/AN7
1 = Input
0 = Output
TRISE1: Direction Control bit for pin RE1/WR/AN6
1 = Input
0 = Output
TRISE0: Direction Control bit for pin RE0/RD/AN5
