Register : Flash Command Write Data Register (Lower) - flashcmdwrdatalo

Description

Register Layout

Bits Access Reset Description
[31:0] RW 0x0 Command Write Data Lower Byte

Field : Command Write Data Lower Byte - data

This is the command write data lower byte. This should be setup before triggering the command with execute field (bit 0) of the Flash Command Control register. It is the data that is to be written to the flash for any status or configuration write operation carried out by triggering the event in the Flash Command Control register.

Data Structure Documentation

struct ALT_QSPI_FLSHCMDWRDATALO_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.
