SENT SPC - introduction SENT SPC (single-edge nibble transmission short PWM code) is a half-duplex variation of the SENT protocol defined by Infineon Technologies AG. It is an extension of the SAE J2716 SENT protocol. It allows on-demand transmission of a single SENT frame by a sensor in the event a controller initiates the transfer of data, by sending a master trigger pulse (MTP).
