Typedef Documentation

typedef struct _FIRMWARE_INFO FIRMWARE_INFO

There are two copies of the firmware in Flash, FirmwareA and FirmwareB. Both have an associated "Firmware Info" sector.

The FirmwareA and FirmwareB both have a Firmware Info structure. 0x0 - 0x7f contains information on the Firmware. 0x80 - 0xfff contains the default configuation data for the firmware (external EEPROM).

!!!!! IMPORTANT !!!!! Ensure this structure is NOT larger than 128 bytes

typedef union _FIRMWARE_STATE FIRMWARE_STATE

Gives the current state of FirmwareA and FirmwareB. Possible conditions are:
