dma

This register is used to enable ECC on the DMA RAM. ECC errors can be injected into the write path using bits in this register. This register contains interrupt status of the ECC single/double bit error. Only reset by a cold reset (ignores warm reset).

Offset: 0x158

Access: RW

Important: To prevent indeterminate system behavior, reserved areas of memory must not be accessed by software or hardware. Any area of the memory map that is not explicitly defined as a register space or accessible memory is considered reserved.

dma Fields

Bit	Name	Description	Access	Reset
4	`derr`	This bit is an interrupt status bit for DMA RAM ECC double bit, non-correctable error. It is set by hardware when double bit, non-correctable error occurs in DMA RAM. Software needs to write 1 into this bit to clear the interrupt status.	`RW`	`0x0`
3	`serr`	This bit is an interrupt status bit for DMA RAM ECC single, correctable error. It is set by hardware when single, correctable error occurs in DMA RAM. Software needs to write 1 into this bit to clear the interrupt status.	`RW`	`0x0`
2	`injd`	Changing this bit from zero to one injects a double, non-correctable error into the DMA RAM. This only injects one double bit error into the DMA RAM.	`RW`	`0x0`
1	`injs`	Changing this bit from zero to one injects a single, correctable error into the DMA RAM. This only injects one error into the DMA RAM.	`RW`	`0x0`
0	`en`	Enable ECC for DMA RAM	`RW`	`0x0`
