PRODUCTION DATA
Sending a RESET command or executing a pin reset using the SYNC/RESET pin disables the DC/DC converter by resetting the DCDC_EN bit to 0b. Therefore, the start-up process following a RESET command or a pin reset using the SYNC/RESET pin is similar to what occurs after power up. However, there is no tPOR_DVDD in the case of a command or pin reset because the DVDD supply is already ramped.
Figure 8-19 shows the behavior after a pin reset using the SYNC/RESET pin. A reset is only generated if the SYNC/RESET pin is held low longer than tw(RSL). If the pin is held low for a duration less then tw(RSL) but greater than a CLKIN period, a synchronization occurs instead of a reset.
As shown in Figure 8-19, follow the same sequence for configuring the device and reading the SEC_FAIL bit in the STATUS register as described in the Start-Up Behavior After Power-UpStart-Up Behavior After Power-UpStart-Up Behavior After Power-UpStart-Up Behavior After a Pin Reset or RESET CommandStart-Up Behavior After a Pin Reset or RESET CommandStart-Up Behavior After Power-UpStart-Up Behavior After a Pin Reset or RESET CommandStart-Up Behavior After a Pause in CLKIN section to receive valid conversion data after a RESET command or a pin reset using the SYNC/RESET pin.
