Detailed Description

SPI Flash instance structure.

Note

This structure holds the instance data, driver and SPI setting for an SPI Flash peripheral.

inst: Pointer to SPI instance used for SPI Flash communication.
info: Pointer to Flash Descriptor structure.
detected_id: Detected JEDEC ID after probing.
cs: Chip select line used for SPI Flash communication.
cmd_rd_status: Command for reading status register.
cmd_wr_status: Command for writing status register.
cmd_exit_4byte: Command for exiting 4-byte addressing mode.
mask_qe: Mask for Quad Enable bit in status register.

All the content such as JEDEC Identifiers, part_no and post_init_hook will be stored in spiFlash_instance_t that user declared initially.
