*************************************************************************** ! FILE NAME : fpgaclocks353.c ! provides control of the FPGA clocks based on 3-pll generator ! Direct r/w of the CY22393 over the I2C interface (connected to PB.16 and PB.17 of the CPU) ! supports 3 PLLs connected to 3 outputs (clk0, clk1 and clk2) ! clk3 can be only turned on to Xtal frequency (12MHz) or off ! Input parameter specifies frequency in Hz, internally data is rounded to 100Hz ! ! !
