Bits [7:6] —Not implemented
Always read zero
DDD[5:0] — Data Direction for Port D
0 = Bits set to zero to configure corresponding I/O pin for input only
1 = Bits set to one to configure corresponding I/O pin for output
NOTE
When the SPI system is in slave mode, DDD5 has no meaning nor effect. When
the SPI system is in master mode, DDD5 determines whether bit 5 of PORTD is an
error detect input (DDD5 = 0) or a general-purpose output (DDD5 = 1). If the SPI
system is enabled and expects any of bits [4:2] to be an input that bit will be an input
regardless of the state of the associated DDR bit. If any of bits [4:2] are expected
to be outputs that bit will be an output
only
if the associated DDR bit is set.
*Not bonded on 64-pin version.
Bits [7:4] — Not implemented
Always read zero
xPPUE — Port x Pin Pull-Up Enable
Refer to PAREN bit in CONFIG register discussed in
6 Parallel Input/Output
.
0 = Port x pin on-chip pull-up devices disabled
1 = Port x pin on-chip pull-up devices enabled
NOTE
FPPUE and BPPUE do not apply in expanded mode because ports F and B are
address outputs.
