Updater commands

Once updater mode is entered, the updater first reports a Blue_Initialized_event, as

described in previous section. Then it continues checking the SPI interface to receive

commands. The updater only responds to certain updater commands, listed below. The

updater supports no other commands. Once entered, the updater will stay in this mode

unless clearly asked to exit by a command (Updater_Reboot) or an HW reset.

For each command, the updater acknowledges with standard Command Complete event.

The commands and events are in the format as the same as other ACI commands.

The updater supports only the following commands:

 Updater_Reboot

 Updater_Version

 Updater_BufferSize

 Updater_EraseBlueFlag

 Updater_ResetBlueFlag

 Updater_EraseSector

 Updater_WriteDataBlock

 Updater_ReadDataBlock

 Updater_CalculateCRC
