PRODUCTION DATA
The PDN pin (active low) can be used for device power down and used to initialize the POR sequence. When PDN is pulled low, the entire device is powered down and the serial interface is disabled. When PDN is pulled high, the device POR sequence is triggered to begin the device start-up sequence and normal operation as depicted in Figure 8-1. If the PDN pin is toggled to issue a momentary hard-reset, the negative pulse applied to the PDN pin must be greater than 200ns to be captured by the internal digital system clock.
