VDDC
88
-
Power Positive supply for most of the logic function, including the
processor core and most peripherals. The voltage on this pin is
1.3 V and is supplied by the on-chip LDO. The VDDC pins should
only be connected to the LDO pin and an external capacitor as
specified in Table 21-6 on page 900.

I/O
TTL
Capture/Compare/PWM 1.
CCP5
I/O
TTL
Capture/Compare/PWM 5.
90
CCP7
I/O
TTL
Capture/Compare/PWM 7.
VREFA
I
Analog This input provides a reference voltage used to specify the input
voltage at which the ADC converts to a maximum value. In other
words, the voltage that is applied to VREFA is the voltage with which
an AINn signal is converted to 4095. The VREFA input is limited
to the range specified in Table 21-26 on page 912 .
