[*] --> Boot: Entry Point

state Boot {
	[*] --> BootInit
	BootInit: Initialize various TI things (gio, spi, etc)
	BootInit --> sciSetBaudrate
	sciSetBaudrate: For BMS communication
	sciSetBaudrate --> BMSInit
	state BMSInit {
		[*] --> Wake
		Wake --> Wake: Loop for every board
		Wake: Assert Wake bit to wake up bq76 BMS boards
		Wake --> InitialConfig
		InitialConfig: (1.2.1) Send 0xF21010E0 to all boards
		InitialConfig --> StartAutoAddress
		StartAutoAddress: (1.2.2) Tell BMSs to use auto addressing, then enter the auto-address mode
		StartAutoAddress --> SetAutoAddress
		SetAutoAddress: (1.2.3) Write the address to the Device Address Register
		SetAutoAddress --> SetAutoAddress: Loop for all boards
		SetAutoAddress --> CheckHeartbeats
		CheckHeartbeats: (1.2.4) Checks to see if all BMSs respond with a heartbeat message (with proper CRC of course). The final check to make sure all boards are alive before doing anything fancy
		CheckHeartbeats --> Wake: RESTART if failed
		CheckHeartbeats --> DisableTopHighRX
		DisableTopHighRX: (1.2.5) Make sure the top-most board doesn't try receiving on a floating port
		DisableTopHighRX --> DisableBottomLowRX
		DisableBottomLowRX: (1.2.6) Same as DisableTopHighRX but for bottom-most board
		DisableBottomLowRX --> ConfigGPIO
		ConfigGPIO: (5.2) Set all GPIO as inputs
		ConfigGPIO --> SetSampleDelay
		SetSampleDelay: (2.2.1) UNKNOWN: Check PDF
		SetSampleDelay --> SetSamplePeriod
		SetSamplePeriod: (2.2.2) UNKNOWN: Check PDF
		SetSamplePeriod --> CheckBMSFaults
		CheckBMSFaults: (2.2.4) Checks BMS boards for any faults
		CheckBMSFaults --> SetChannels
		SetChannels: (2.2.5.2) Tell BMSs how many channels (16) to use (CHECK MORE DOCUMENTATION)
		ClearFaults: (1.2.7) Clear all faults from the individual BMS boards
