(Please visit the site to view this file)Hello Hitesh, I am currently investigating the behavior you've stated. Meanwhile there are some other issues that need to be addressed: 1. Baud rate concerns UART mode, not SPI, so your UCA0BRW is simply a bit clock prescalar and not a modulation control. 2. Please refer to Figure 3 of the device datasheet. You must increase your PMMCOREV settings up to at least 2 (in order, or level-by-level, and with the proper SVM & SVS changes) in order to operate at a 16 MHz system frequency. An example of how this can be done is attached. 3. You are using 3-wire SPI mode so the CS pin is not necessarily important regarding USCI master behavior, it is typically low for active and high for inactive. Regards, Ryan
