; (000) Reset Cycle

; (000) Reset Cycle

: The reset cycle resets the selected chips.  There are flags for resetting all 4 chips: DAC, ADC, temperature sensor, Ethernet controller.  This is the entry state from a power-on.  From this state, proceed unconditionally to 001.

; (001) Transmit "I"

; <s>(001) Transmit "I"</s>

: This state transmits an "I" packet to acknowledge that a reset occurred but the board is now prepared to accept new packets and function normally. From this state, proceed unconditionally to 010.

: <s>This state transmits an "I" packet to acknowledge that a reset occurred but the board is now prepared to accept new packets and function normally. From this state, proceed unconditionally to 010.</s> "S"-Packet (from state 101) would do just as well, returning zeroed registers, location address etc for computer's address LUT.

; (010) Idle

; (010) Idle

: This is the idle state where the state machine awaits a new packet's arrival.  If the Receive FIFO is empty, it loops back on itself and continues checking the FIFO.  If the FIFO is not empty, proceed to 011.
