Enumeration Type Documentation

boot_flash_bank

enum boot_flash_bank

#include <zephyr/drivers/flash/mchp_nvmctrl_g3.h>

Boot Flash Memory (BFM) bank selection.

This enumeration defines the available boot flash memory banks/panels. The boot flash memory can be organized into multiple banks for redundancy and fail-safe boot operations.

Enumerator
BOOT_FLASH_BANK_1	Boot Flash Memory Bank/Panel 1.
BOOT_FLASH_BANK_2	Boot Flash Memory Bank/Panel 2.

flash_mchp_ex_ops_t [1/2]

enum flash_mchp_ex_ops_t

#include <zephyr/drivers/flash/mchp_nvmctrl_g2.h>

This enumeration defines the set of extended operations that can be performed on the flash memory, such as erasing or writing the user row, and locking or unlocking specific flash regions.

Enumerator
FLASH_EX_OP_REGION_LOCK	Lock a specific region.
FLASH_EX_OP_REGION_UNLOCK	Unlock a specific region.
FLASH_EX_OP_SET_PWR_REDUCTION_MODE	Sets the Power Reduction mode.
FLASH_EX_OP_CLR_PWR_REDUCTION_MODE	Clears the Power Reduction mode.
FLASH_EX_OP_CLR_PAGE_BUFFER	Clears the flash page buffer.
FLASH_EX_OP_SET_SECURITY_BIT	Set Security Bit.
FLASH_EX_OP_INVALIDATE_CACHE_LINES	Invalidates all cache lines.
FLASH_EX_OP_SET_CHIP_ERASE_HARDLOCK	Set Chip Erase Hard Lock.

flash_mchp_ex_ops_t [2/2]

enum flash_mchp_ex_ops_t

#include <zephyr/drivers/flash/mchp_nvmctrl_g3.h>

This enumeration defines the set of extended operations that can be performed on the flash memory, such as erasing or writing the user row, and locking or unlocking specific flash regions.

Enumerator
FLASH_EX_OP_PFM_REGION_WRITE_PROTECT_ENABLE	Enable write protection for a PFM region.
FLASH_EX_OP_PFM_REGION_WRITE_PROTECT_DISABLE	Disable write protection for a PFM region.
FLASH_EX_OP_PFM_REGION_WRITE_PROTECT_LOCK	Lock write protection settings for a PFM region.
FLASH_EX_OP_BFM_WRITE_PROTECT_ENABLE	Enable write protection for BFM.
FLASH_EX_OP_BFM_WRITE_PROTECT_DISABLE	Disable write protection for BFM.
FLASH_EX_OP_BFM_WRITE_PROTECT_LOCK	Lock write protection settings for BFM.

pfm_wp_region

enum pfm_wp_region

#include <zephyr/drivers/flash/mchp_nvmctrl_g3.h>

Program Flash Memory (PFM) write protection regions.

This enumeration defines the available write protection regions for the Program Flash Memory. Each region can be independently configured for write protection.

Enumerator
PFM_WP_REGION_0	PFM write protection region 0.
PFM_WP_REGION_1	PFM write protection region 1.
PFM_WP_REGION_2	PFM write protection region 2.
PFM_WP_REGION_3	PFM write protection region 3.
PFM_WP_REGION_4	PFM write protection region 4.
PFM_WP_REGION_5	PFM write protection region 5.
PFM_WP_REGION_6	PFM write protection region 6.
PFM_WP_REGION_7	PFM write protection region 7.
