6.6.2 PIN DESCRIPTIONS
Each PORTE pin is multiplexed with other functions. The
pins and their combined functions are briefly described
here. For specific information about individual functions
such as the SSP, I
2
C or interrupts, refer to the appropriate
section in this data sheet.
6.6.2.1 RE0/AN5/CPSA5
These pins are configurable to function as one of the
following:
• General purpose I/O
• Analog input for the ADC
• Capacitive sensing input
6.6.2.2 RE1/AN6/CPSA6
These pins are configurable to function as one of the
following:
• General purpose I/O
• Analog input for the ADC
• Capacitive sensing input
6.6.2.3 RE2/AN7/CPSA7
These pins are configurable to function as one of the
following:
• General purpose I/O
• Analog input for the ADC
• Capacitive sensing input

TRISE3 TRISE2 TRISE1 TRISE0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-4 Unimplemented: Read as ‘0’
bit 3 TRISE3: RE3 Port Tri-state Control bit
This bit is always ‘1’ as RE3 is an input only
bit 2-0 TRISE<2:0>: RE<2:0> Tri-State Control bits
(1)
1 = PORTE pin configured as an input (tri-stated)
0 = PORTE pin configured as an output

ANSE2 ANSE1 ANSE0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-3 Unimplemented: Read as ‘0’
bit 2-0 ANSE<2:0>: Analog Select between Analog or Digital Function on Pins RE<2:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
(1)
. Digital input buffer disabled.
Note 1: When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to
allow external control of the voltage on the pin.
