Description

The PIC16F84A belongs to the mid-range family of the PICmicro microcontroller devices. The program memory contains 1K words, which translates to 1024 instructions, since each 14-bit program memory word is the same width as each device instruction. The data memory (RAM) contains 68 bytes. Data EEPROM is 64 bytes. There are also 13 I/O pins that are user-configured on a pin-to-pin basis. Some pins are multiplexed with other device functions. These functions include:

1. External interrupt
2. Change on PORTB interrupt
3. Timer0 clock input
