PIC Microcontroller USART (Asynchronous ) transmission Steps
- Initialize the SPBRG register for the appropriate baud rate. In the case high speed baud rate is rquired, set bit BRGH.
- Dont forget to enable the asynchronous serial port by clearing bit SYNC and setting bit SPEN.
- For interrupt based transmission enable bit TXIE.
- For 9-bit transmission is desired, then set transmit bit TX9.
- Enable the transmission by setting bit TXEN, which will also set bit TXIF.
- If 9-bit transmission is selected, the ninth bit should be loaded in bit TX9D.
- Load data to the TXREG register (starts transmission). It is to be noted, transmission starts immediately after TXREG is loaded.
- If using interrupts, ensure that GIE bit and PEIE bit (bits 7 and 6 of the INTCON register) are set.

PCB Design Rules for Sensitive Circuits to avoid EMI problems
- Keep the tracks length as short as possible
- Do not route the analog signal and the digital signal together
- Keep the clock track separate from the other signal
- Keep the high frequency signals tracks separate from the other signals.
- Keep the Ground track as short as possible.
- Keep the lengths of the connector short of high frequency signals such as SPI clock (!important)
- Do not turn the route at 90o.
- Never run the clock signal tracks to outer edge of the PCB
- No unrelated component should be closer than 1 inch to the crystal
- Put the crystal not farther than 1 cm form oscillator pin
- Put RBIAS resistor as close as possible to pin.
