Register : rescan_buffer_flag

Description

Rescan buffer flag.

Register Layout

Bits Access Reset Description
[3:0] RW 0x0 ALT_NAND_DMA_RESCAN_BUF_FLAG_FLAG
[31:4] ??? Unknown UNDEFINED

Field : flag

This register can be used to force rescan of buffer flags in any of the cmd-dma channels.

The bit index decides the Channel number. Cmd-dma would rescan the buffer flag for matching

condition and it executes the descriptor if it is ready. Hardware clears this register after

generating the trigger event.

struct ALT_NAND_DMA_RESCAN_BUF_FLAG_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
