Correct connectivity for bypass mode - MKW41Z

Hi,

There is an inconsistency between the MKW41Z reference manual and AN5025 in regards to how to select bypass mode.

In the reference manual it says to connect both PSWITCH and DCDC_CFG to GND, while the application note (confirmed by the FRDM-MKW41Z schematics as well) sets PSWITCH to GND and DCDC_CFG to VCC.

Thanks!

Alex

Hi,

I am not sure which reference manual do you review. But in MKW41Z512RM, its description is same as the AN5025

Have a great day,
TIC

In this document here: https://www.nxp.com/files-static/32bit/doc/ref_manual/MKW41Z512RM.pdf?&fasp=1&WT_TYPE=Reference%20Manuals&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation&fileExt=.pdf

Just saw that it's a very early version and that the latest one is indeed correct, as you pointed out. Thanks!
