Function Documentation

zynq_slcr_fpga_clk_rst()

void zynq_slcr_fpga_clk_rst

(

uint32_t

val

)

Control the FPGA reset values.

Parameters

val	Bits 0 through 3 correspond to FPGA RST 0 through 3. A bit value of 1 asserts the reset.

zynq_slcr_fpga_clk_rst_mask_set()

void zynq_slcr_fpga_clk_rst_mask_set

(

uint32_t

mask

)

Set the mask that allows the FPGA resets to be modified.

Bit 0 corresponds to FPGA0_OUT_RST, and bit 3 to FPGA3_OUT_RST. Setting a bit in the mask to 1 allows calls to zynq_slcr_fpga_clk_rst to modify that reset. The default mask is 0xf.

zynq_slcr_level_shifter_enable()

void zynq_slcr_level_shifter_enable

(

uint32_t

val

)

Control the level shifters between the PS and PL.

Parameters

val	Acceptable values are ZYNQ_SLCR_LVL_SHFTR_EN_DISABLE, ZYNQ_SLCR_LVL_SHFTR_EN_PS_TO_PL, and ZYNQ_SLCR_LVL_SHFTR_EN_ALL.
