int ice_fpga_stop(const ice_fpga fpga)
Set the ICE_FPGA_CRESET_B_PIN to LOW which keeps the FPGA in reset mode.
int ice_fpga_start(const ice_fpga fpga)
Release the stop mode if it was present, and wait that the FPGA confirms its startup with ICE_FPGA_CD...
int ice_fpga_deinit(const ice_fpga fpga)
deinit and free FPGA and associated resources
int ice_fpga_init(const ice_fpga fpga, uint8_t freq_mhz)
Let the FPGA start and export a clock for it over ICE_FPGA_CLOCK_PIN.
