[31:0] | RW | 0x0 | Watermark Value |
Field : Watermark Value - level | |
This represents the minimum fill level of the SRAM before a DMA peripheral access is permitted. When the SRAM fill level passes the watermark, an interrupt is also generated. This field can be disabled by writing a value of all zeroes. Field Access Macros: | |

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.
