Functions
void	runStateMachine (void)
	function executes different states of the system. SYS_SND_ADDRS_RANGE - Send the PIC programmable start and end address of the program memory SYS_WAIT_FOR_START_CMND - The Start command triggers system to start the process and initializes buffer counter SYS_RCV_FIRMWARE_HEADER - Get the total packet count from the host and applcn start address SYS_CONFIG_FLASH - Erase application program area and update table pointer SYS_FIRMWARE_UPDATE - Receive and put the binary chunks in the flash memory SYS_RUN_APPLCN - Run the application

void	initVarConfigPort (void)

void	runApplcn (void)
	PC is updated with the new pointer to execute loaded binary from the application flash program memory.

Enumeration Type Documentation

§ SYSTEM_COM_PROTOCOL_MSG_Tag

enum SYSTEM_COM_PROTOCOL_MSG_Tag

Enumeral represents handshaking signals between programmer and controller.

Enumerator
SYS_START_CMND_FROM_PROGRMR	Config command signal from the programmer.
SYS_READY_FOR_FIRMWARE_HEADER	Ready for firmware header signal sent to the programmer.
SYS_FIRMWARE_HEADER_POS_ACK	Firmware header positive acknowledgement.
SYS_FIRMWARE_HEADER_NEG_ACK	Firmware header negative acknowledgement.
SYS_SND_NXT_CHUNK	send next chunk signal.
SYS_ADDRESS_RANGE_TAG	send address with this tag.
SYS_ADDRESS_RANGE_RQT	Rquest for the address from the host.

§ SYSTEM_STATUS_Tag

enum SYSTEM_STATUS_Tag

Enumeral represents different system states.

Enumerator
SYS_WAIT_FOR_START_CMND	State where system waits for a start command from the programmer.
SYS_CONFIG_FLASH	State where system configs flash
SYS_RCV_FIRMWARE_HEADER	State where system waits for firmware header from the programmer
SYS_FIRMWARE_UPDATE	State where system loads the binary into the NVM
SYS_RUN_APPLCN	State where system jumps to the application
SYS_SND_ADDRS_RANGE	State where the system sends the PIC programmable start and end address of the program memory

Variable Documentation
