(CRC verification is normal, and the oscilloscope has checked that there is no fluctuation in the output voltage.)<BR />3: In debug mode, clearing the wake-up source and configuring the wake-up source ensures that the wake-up source is currently at a low level,<BR />Call Sbc again_ Fs26_ SetOperatingMode failed to enter LPOFF mode, and the output voltage was checked through an oscilloscope without any fluctuations.</P> Fri, 17 Nov 2023 01:53:55 GMT shiqi_seventeen 2023-11-17T01:53:55Z https://community.nxp.com/t5/Other-NXP-Products/FS2633-WAKE-UP/m-p/1758697#M20135 <P>Hello Team, I am using FS2633, there are three questions about FS26 LPOFF mode wake-up :<BR />FS26 LPOFF mode wake-up issue, 0x57 register read value=0x2009:<BR />1: Power on to call Sbc_ Fs26_ The SetOperatingMode function allows you to enter LPOFF mode normally.<BR />2: After powering on and operating other registers, call Sbc again_ Fs26_ The SetOperatingMode function is invalid when it enters LPOFF.
