TMS37157: TMS37157 reset functionality

subin s

Part Number: TMS37157

Hi, Can someone tell me the function on NPOR pin on TMS37157. Can it be controlled through an LF Command, so that i can reset a microcontroller through LF command just in case if it gets hang.

Thanks,

Dear subin s -

please first see pin description on page 3 of the datasheet, then page 42 in same for the schematic, for when it is used -

i think if you send a General Read command to Page 25 of the device (from the LF side), it should generate the RESET you can use with the MCU

Hi Josh,

I use PalFi Kit as reader for testing , i found page 25 is not accessible through GUI. Also TMS 37157 datasheet has no reference to Page 25. Pls suggests me how can i access Page 25. Is it possible with PalFI development kit?

thanks
