EDMA3 PaRAM Set. More...

#include <edma3_rm.h>

Data Fields
volatile unsigned int	OPT
volatile unsigned int	SRC
	Starting byte address of Source For FIFO mode, srcAddr must be a 256-bit aligned address.
volatile unsigned int	A_B_CNT
volatile unsigned int	DST
	Starting byte address of destination For FIFO mode, destAddr must be a 256-bit aligned address. i.e. 5 LSBs should be 0.
volatile unsigned int	SRC_DST_BIDX
volatile unsigned int	LINK_BCNTRLD
	Address for linking (AutoReloading of a PaRAM Set) (16 bits) and Reload value of the numArrInFrame (BCNT) (16 bits).
volatile unsigned int	SRC_DST_CIDX
	Index between consecutive frames of a Source Block (SRCCIDX) (16 bits) and Index between consecutive frames of a Dest Block (DSTCIDX) (16 bits).
volatile unsigned int	CCNT
	Number of Frames in a block (CCNT) (16 bits).

Detailed Description

EDMA3 PaRAM Set.

This is a mapping of the EDMA3 PaRAM set provided to the user for ease of modification of the individual PaRAM words.

It could be used by the advanced users to program the PaRAM Set directly, without using any API.

Field Documentation

volatile unsigned int EDMA3_RM_ParamentryRegs::A_B_CNT

Number of bytes in each Array (ACNT) (16 bits) and Number of Arrays in each Frame (BCNT) (16 bits).

volatile unsigned int EDMA3_RM_ParamentryRegs::LINK_BCNTRLD

Address for linking (AutoReloading of a PaRAM Set) (16 bits) and Reload value of the numArrInFrame (BCNT) (16 bits).

Link field must point to a valid aligned 32-byte PaRAM set A value of 0xFFFF means no linking.

B count reload field is relevant only for A-sync transfers.

volatile unsigned int EDMA3_RM_ParamentryRegs::OPT

OPT field of PaRAM Set

volatile unsigned int EDMA3_RM_ParamentryRegs::SRC_DST_BIDX

Index between consec. arrays of a Source Frame (SRCBIDX) (16 bits) and Index between consec. arrays of a Destination Frame (DSTBIDX) (16 bits).

If SAM is set to 1 (via channelOptions) then srcInterArrIndex should be an even multiple of 32 bytes.

If DAM is set to 1 (via channelOptions) then destInterArrIndex should be an even multiple of 32 bytes
