详细描述

This union represents the bit fields in the SFC command config Register.
Read the register into the d32 member then set/clear the bits using the b elements.

结构体成员变量说明

addr_en

uint32_t cmd_config::addr_en

Indicates whether an address is available for this operation.

[struct] [1/2]

struct { ... } cmd_config::b

Register bits.

[struct] [2/2]

struct { ... } cmd_config::b

Register bits.

d32

uint32_t cmd_config::d32

Raw register data.

data_cnt

uint32_t cmd_config::data_cnt

Data transfer length of the SPI operation. Data length = (data_cnt + 1) Byte.

data_en

uint32_t cmd_config::data_en

Indicates whether data is available for this operation.

dummy_byte_cnt

uint32_t cmd_config::dummy_byte_cnt

Number of dummy bytes in the operation.

mem_if_type

uint32_t cmd_config::mem_if_type

SPI interface type. value: 000：Standard SPI; 001：Dual-Input/Dual-Output SPI(based on read/write); 010：Dual-I/O SPI; 101：Quad-Input/Dual-Output SPI(based on read/write); 110：Quad-I/O SPI; other: reserved.

reserved

uint32_t cmd_config::reserved

reserved0

uint32_t cmd_config::reserved0

reserved1

uint32_t cmd_config::reserved1

rw

uint32_t cmd_config::rw

SPI read/write indicator. 0: write; 1: read.

sel_cs

uint32_t cmd_config::sel_cs

CS select operation.

start

uint32_t cmd_config::start

SPI transfer enable control. Automatic return to 0 after the SPI transfer is complete.
