Firmware documentation for Tire Pressure Monitor Sensor (TPMS) MPXx85/86xxD?

[jonathanfeucht]

I am trying to develop my first applications for the MPXY8500B chip. I have attained the datasheet on the Freescale web site, however, it merely lists the firmware routines (TPMS_RESET, TPMS_READ_VOLTAGE) and the address of the routines, however it does not give complete details for each routine, namely what the parameters are, what the expected return values are, and the side effects of the routine. Where can I at least find a list of function prototypes for these routines? Even better, where can I locate the source code?

Hi Jonathan,

Unfortunately the requested information is under NDA license agreement and I’m not authorized to send it, you will need to contact your sales representative, FAE or distributor to sign the required NDA to get this kind of document.

Ask for the “MPXx85/86xxxD Embedded Firmware User Guide”.

Regards,

Jose
