Function Documentation

u32 XSem_EbdLookUp	(	u8	BtIndex,
		u8	RowIndex,
		u32	FAddr,
		u32	QwordIndex,
		u32	BitIndex,
		volatile int *	XSem_EbdBuffer
	)

This API can be used to check whether a particular bit is an Essential bit or not.

Parameters

BtIndex[In]

: Block type (Valid Inputs: 0, 3, 4, 5) RowIndex[In] : Row (Valid Inputs: 0 to 3) FAddr[In] : Frame Address (Valid Inputs: Refer note) QwordIndex[In] : Qword (Valid Inputs: 0 to 24) BitIndex[In] : Bit (Valid Inputs: 0 to 127) XSem_EbdBuffer : Pointer to golden EBD data buffer

Returns

0U : Input Bit is essential 1U : Input Bit is not essential 2U : Invalid Input

Note

• Total number of frames in a row is not same for all rows.
• XSem_CmdCfrGetTotalFrames API is provided to know the total number of frames in a row for each block. Output param (FrameCntPtr) of XSem_CmdCfrGetTotalFrames API is updated with total number of frames of each block type for the input row. If a particular block in a row has 0 frames, then error injection shall not be performed. Range of Frame number: 0 to (FrameCntPtr[n] - 1) where n is block type with range 0 to 6.

Check if Input bit is set or not, If Set, then the bit is essential, else, not essential
