Instructions for Using PIC16F689T-I/SS
Power Supply:
- Connect Vdd (pin 20) to the positive supply voltage (2.0V to 5.5V).
- Connect Vss (pin 10) to ground.
Oscillator Configuration:
- Use the OSCCON register to configure the internal oscillator.
- For external oscillators, connect the appropriate crystal or resonator to the OSC1 (pin 1) and OSC2 (pin 2) pins.
Reset Pin (MCLR):
- Connect MCLR (pin 19) to Vdd through a pull-up resistor (e.g., 10kΩ).
- Optionally, use a push-button switch to ground for manual reset.
Programming:
- Use an in-circuit programmer (ICP) or an external programmer compatible with the PIC16F689.
- Ensure the programming voltage (Vpp) is applied to the MCLR pin during programming.
I/O Configuration:
- Configure I/O pins using the TRIS registers (TRISA, TRISC).
- Set the direction of each pin (input or output) by writing to the TRIS registers.
Timer Configuration:
- Use the T0CON, T1CON, and T2CON registers to configure the timers.
- Set the prescaler and mode for each timer as needed.
ADC Configuration:
- Use the ADCON0 and ADCON1 registers to configure the ADC.
- Select the input channel and start the conversion by setting the appropriate bits.
Comparator Configuration:
- Use the CMCON register to configure the comparators.
- Set the input and output configurations for each comparator.
USART Configuration:
- Use the BAUDCON, TXSTA, and RCSTA registers to configure the USART.
- Set the baud rate, transmission mode, and receive mode.
Brown-out Reset (BOR):
- Configure the BOR settings in the configuration bits.
- Enable or disable BOR based on the application requirements.
Watchdog Timer (WDT):
- Use the WDTCON register to configure the watchdog timer.
- Enable or disable the WDT and set the timeout period.
Low-Voltage Programming (LVP):
- Configure LVP in the configuration bits.
- Enable or disable LVP based on the programming method and application requirements.
Power Management:
- Use the SLEEP instruction to enter low-power sleep mode.
- Wake up from sleep mode using interrupts or external signals.
Interrupts:
- Use the INTCON register to enable and manage interrupts.
- Configure individual interrupt sources and their priorities.
EEPROM Data Memory:
- Use the EECON1 and EECON2 registers to read from and write to EEPROM.
- Follow the specific sequence for EEPROM operations to ensure data integrity.
By following these instructions, you can effectively use the PIC16F689T-I/SS microcontroller in your projects.
