◆ nvs

struct nvs_device spi_device::nvs

NVS device.

◆ bus

struct spi_bus* spi_device::bus

SPI bus to which device is attached.

Definition at line 90 of file spi.h.

Referenced by falcon_init_spi_device(), natsemi_init_eeprom(), realtek_detect(), and realtek_probe().

◆ slave

unsigned int spi_device::slave

Slave number.

Definition at line 92 of file spi.h.

◆ command_len

unsigned int spi_device::command_len

Command length, in bits.

Definition at line 94 of file spi.h.

◆ address_len

unsigned int spi_device::address_len

Address length, in bits.

Definition at line 96 of file spi.h.

◆ munge_address

unsigned int spi_device::munge_address

Address is munged.

Some devices with 9-bit addresses (e.g. AT25040A EEPROM) use bit 3 of the command byte as address bit A8, rather than having a two-byte address. If this flag is set, then commands should be munged in this way.
