IBF
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
1 = The output buffer still holds a previously written word
0 = The output buffer has been read
1 = A write occurred when a previously input word has not been read (must be cleared in
0 = No overflow occurred
PSPMODE: Parallel Slave Port Mode Select bit
1 = PORTD functions in Parallel Slave Port mode
0 = PORTD functions in general purpose I/O mode
Unimplemented: Read as ‘0’
PORTE Data Direction Bits:
Bit 2: Direction Control bit for pin RE2/CS/AN7
1 = Input
0 = Output
Bit 1: Direction Control bit for pin RE1/WR/AN6
1 = Input
0 = Output
Bit 0: Direction Control bit for pin RE0/RD/AN5
1 = Input
0 = Output
