Block 000 will have four functional blocks: one each for the DAC, ADC, and Ethernet controller, and one to coordinate their completion. The temperature sensor lacks an external reset function; it self-initializes on startup. The "R" packet will supply flags as to whether or not to enable the various blocks. A power-on reset will default to resetting all components. Using the enable flags like a mask on the done lines, the fourth functional block will update the state register. For information on the reset procedures, see [[Reset and Initialization]].
