- Only 4 pins of Port E can be used on a 16F1937 device
- RE0-RE3 can be used as digital inputs
- RE0-RE2 can be used as digital outputs (RE3 can be an input only)
- RE3 is often used as the MCLR pin (i.e. reset) and may not be available to use as an input
- AN5-AN7 can be used as analogue inputs (= 3 analogue inputs on port E)
- The pins of Port E are mapped on the 16F1937 microcontroller as on this drawing
- The pins of Port E are connected to the 9-pin D-type connector of Port E on the multiprogrammer board.
This port is connected to the rest of the PICmicro internals by an 8-bit bus system.
