Register 10-1: TRISE Register
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
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'
TRISE2: RE2 direction control bit
1 = Input
0 = Output
TRISE1: RE1 direction control bit
1 = Input
0 = Output
TRISE0: RE0 direction control bit
1 = Input
0 = Output
