I am not able to set the PLL CTL and PLL DIV Register- ADSP BF548 custom board.

Hi,

User-programmable value divides the VCO signal to generate the system clock (SCLK). You can calculate SCLK by using below formula SCLK = VCO/PLL_DIV.SSEL

VCO is calculated by VCO = (SYS_CLKIN frequency/(DF+1)) MSEL. Please refer " 18 DYNAMIC POWER MANAGEMENT " in below linked HRM:www.analog.com/.../ADSP-BF54x_hwr_rev1.2.pdf

Attached SPI transmission and reception example for BF592 across 2 EZkits. You can refer this for BF548.

Hello, I'm setting a serial clock for an SPI2 device using the code below.
If anyone could help, it would be greatly appreciated. Tell me what I'm doing incorrectly and why a decent serial clock isn't being generated.
Can someone kindly offer some advice on the steps I should take to put the SPI2 device up as a slave so that it produces the 25 MHz serial clock I need?
