Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

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’

bit 2

TRISE2: RE2 Direction Control bit

1 = Input

0 = Output

bit 1

TRISE1: RE1 Direction Control bit

1 = Input

0 = Output

bit 0

TRISE0: RE0 Direction Control bit

1 = Input

0 = Output
