PORTC, TRISC and LATC
Registers
PORTC is an 8-bit wide, bidirectional port. The corre-
sponding Data Direction register is TRISC. Setting a
TRISC bit (= 1) will make the corresponding PORTC
pin an input (i.e., put the corresponding output driver in
a High-Impedance mode). Clearing a TRISC bit (= 0)
will make the corresponding PORTC pin an output (i.e.,
put the contents of the output latch on the selected pin).
The Data Latch register (LATC) is also memory
mapped. Read-modify-write operations on the LATC
register read and write the latched output value for
PORTC.
PORTC is multiplexed with several peripheral functions
(see Table 10-7). The pins have Schmitt Trigger input
buffers.
When enabling peripheral functions, care should be
taken in defining TRIS bits for each PORTC pin. Some
peripherals override the TRIS bit to make a pin an output,
while other peripherals override the TRIS bit to make a
pin an input. The user should refer to the corresponding
peripheral section for additional information.
Pins, RC4 and RC5, are multiplexed with the USB
module. Depending on the configuration of the module,
they can serve as the differential data lines for the on-
chip USB transceiver, or the data inputs from an external
USB transceiver. When used as general purpose inputs,
both RC4 and RC5 input buffers depend on the level of
the voltage applied to the VUSB pin, instead of VDD, like
all other general purpose I/O pins. Therefore, if the RC4
or RC5 general purpose input capability will be used, the
VUSB pin should not be left floating.
Unlike other PORTC pins, RC4 and RC5 do not have
TRISC bits associated with them. As digital ports, they
can only function as digital inputs. When configured for
USB operation, the data direction is determined by the
configuration and status of the USB module at a given
time. If an external transceiver is used, RC4 and RC5
always function as inputs from the transceiver. If the on-
chip transceiver is used, the data direction is determined
by the operation being performed by the module at that
time.
The contents of the TRISC register are affected by
peripheral overrides. Reading TRISC always returns
the current contents, even though a peripheral device
may be overriding one or more of the pins.
EXAMPLE 10-4:
INITIALIZING PORTC
Note:
On a Power-on Reset, PORTC pins
(except RC2, RC4 and RC5) are config-
ured as digital inputs. RC2 will default as
an analog input (controlled by the
ANCON1 register). To use pins, RC4 and
RC5, as digital inputs, the USB module
must be disabled (UCON<3> = 0) and the
on-chip USB transceiver must be dis-
abled (UCFG<3> = 1). The internal USB
transceiver has a POR value of enabled.
