Detailed Description

Extended operations for IT51XXX flash controllers.

Enumeration Type Documentation

Enumeration for IT51XXX flash extended operations.

Defines which flash device is accessed by IT51XXX flash controller, and the addressing mode for IT51XXX flash operations.

Enumerator
FLASH_IT51XXX_INTERNAL	Access the internal SPI e-flash. This operation targets the on-chip embedded SPI flash integrated inside the IT51XXX SoC.
FLASH_IT51XXX_EXTERNAL_FSPI_CS0	Access the external SPI flash connected to FSPI CS0#. This operation targets an external flash device connected to the IT51XXX FSPI controller chip select 0.
FLASH_IT51XXX_EXTERNAL_FSPI_CS1	Access the external SPI flash connected to FSPI CS1#. This operation targets an external flash device connected to the IT51XXX FSPI controller chip select 1.
FLASH_IT51XXX_ADDR_3B	3-byte (24-bit) addressing mode. This mode supports flash devices up to 16MB capacity, using 24-bit address cycles.
FLASH_IT51XXX_ADDR_4B	4-byte (32-bit) addressing mode. This mode supports larger flash devices (>16MB capacity), requiring 32-bit address cycles.
