This is GPS Matlab findPreambles finds the first preamble occurrence in the bit stream of each channel. The preamble is verified by check of the spacing between preambles [6sec] and parity checking of the first two words in a subframe. At the same time function returns list of channels, that are in tracking state and with valid preambles in the nav data stream.

This example sets up the PLL in x10/2 mode, divides SYSCLKOUT by six to reach a 25Mhz HSPCLK (assuming a 30Mhz XCLKIN). The clock divider in the ADC is not used so that the ADC will see the 25Mhz on the HSPCLK. Interrupts are enabled and the EVA is setup to generate a periodic ADC SOC on SEQ1. Two channels are converted, ADCINA3 and ADCINA2.
