Function Documentation

void PLU_Init

(

PLU_Type *

base

)

Note

This API should be called at the beginning of the application using the PLU driver.

Parameters

base	PLU peripheral base address

void PLU_Deinit

(

PLU_Type *

base

)

Parameters

base	PLU peripheral base address

static void PLU_SetLutInputSource ( PLU_Type *  base, plu_lut_index_t  lutIndex, plu_lut_in_index_t  lutInIndex, plu_lut_input_source_t  inputSrc  )

inlinestatic

Note: An external clock must be applied to the PLU_CLKIN input when using FFs. For each LUT, the slot associated with the output from LUTn itself is tied low.

Parameters

base	PLU peripheral base address.
lutIndex	LUT index (see plu_lut_index_t typedef enumeration).
lutInIndex	LUT input index (see plu_lut_in_index_t typedef enumeration).
inputSrc	LUT input source (see plu_lut_input_source_t typedef enumeration).

static void PLU_SetOutputSource ( PLU_Type *  base, plu_output_index_t  outputIndex, plu_output_source_t  outputSrc  )

inlinestatic

Note: An external clock must be applied to the PLU_CLKIN input when using FFs.

Parameters

base	PLU peripheral base address.
outputIndex	PLU output index (see plu_output_index_t typedef enumeration).
outputSrc	PLU output source (see plu_output_source_t typedef enumeration).

static void PLU_SetLutTruthTable ( PLU_Type *  base, plu_lut_index_t  lutIndex, uint32_t  truthTable  )

inlinestatic

Parameters

base	PLU peripheral base address.
lutIndex	LUT index (see plu_lut_index_t typedef enumeration).
truthTable	Truth Table value.

static uint32_t PLU_ReadOutputState ( PLU_Type *  base )

inlinestatic

Note: The PLU bus clock must be re-enabled prior to reading the Outpus Register if PLU bus clock is shut-off.

Parameters

base	PLU peripheral base address.

Returns

Current PLU output state value.
