PRODUCTION DATA.
Figure 35 illustrates the relationships between device states, the control pins, device initialization and configuration, and device operational modes. In pin mode, the state of the control pins determines the configuration of the device for all device states. In programming mode, the device registers are initialized to their default state and the host can update the configuration by writing to the device registers.
A system may transition a device from pin mode to host connected mode by changing the state of the SI_MODE pins and then triggering a device power cycle by toggling the PDN input pin (high-low-high); however, outputs will be disabled during the transition as the device registers are initialized to the host mode default state.
