Register : Flash Command Read Data Register (Lower) - flashcmdrddatalo

Description

Register Layout

Bits Access Reset Description
[31:0] RW 0x0 Command Read Data (Lower byte)

Field : Command Read Data (Lower byte) - data

This is the data that is returned by the flash device for any status or configuration read operation carried out by triggering the event in the control register. The register will be valid when the polling bit in the control register is low.

Data Structure Documentation

struct ALT_QSPI_FLSHCMDRDDATALO_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.
