85 / 160 page  © 1999 Microchip Technology Inc. Preliminary DS40300B-page 85 PIC16F62X Steps to follow when setting up a Synchronous Master Transmission: 1. Initialize the SPBRG register for the appropriate baud rate (Section 12.1). 2. Enable the synchronous master serial port by setting bits SYNC, SPEN, and CSRC. 3. If interrupts are desired, then set enable bit TXIE. 4. If 9-bit transmission is desired, then set bit TX9. 5. Enable the transmission by setting bit TXEN. 6. If 9-bit transmission is selected, the ninth bit should be loaded in bit TX9D. 7. Start transmission by loading data to the TXREG register.
