PORT A

<^< 16F1937 Architecture | Course Index | PORT B >^>

• All 8 pins of Port A can be used on a 16F1937 device
• RA0-RA7 can be used as digital inputs
• RA0-RA7 can be used as digital outputs
• RA6-RA7 are often used for an external oscillator and may not be available as i/o
• AN0-AN4 can be used as analogue inputs (=5 analogue inputs on port A)

• The pins of port A are mapped on the 16F1937 microcontroller as on this drawing

• The pins of Port A are connected to the 9-pin D-type connector of Port A on the Multiprogrammer board.

This port is connected to the rest of the PICmicro internals by an 8-bit bus system.
