Table 5. OE Pin Function Summary Pin Function
OE1: OUT1 OE1 only control OUT1 enable/disable, other outputs are not affected by this pin status. OE2: OUT2 OE2 only control OUT2 enable/disable, other outputs are not affected by this pin status. OE1 control chip global power down (PD#) except 32.768kHz on OE1 (when 32K is enabled), When the PD# pin is active OE1: PD# low, the chip goes to lowest power down mode and all outputs are disabled except 32kHz output, and only keeps 32k/Xtal calibration. OE1: OUT1_PPS Config OE1 as OUT1_PPS (Proactive Power Saving) function pin. OE2: OUT2_PPS Config OE2 as OUT2_PPS (Proactive Power Saving) function pin. OE1:DFC0 Config OE1 as DFC0 control pin 0. OE2:DFC1 Config OE2 as DFC1 control pin 1.
