The sensor supports a SPC (Short PWM Code) protocol, which enhances the
standardized SENT protocol (Single Edge Nibble Transmission) defined by SAE J2716.
SPC enables the use of enhanced protocol functionality due to the ability to select
between “synchronous”, “range selection” and “ID selection” protocol mode. The
following tables give an overview of relevant registers to chose the appropriate SPC
mode.

As in SENT, the time between two consecutive falling edges defines the value of a four
bit nibble, thus representing numbers between 0 and 15. The transmission time therefore
depends on the transmitted data values.The single edge is defined by a 3 unit time (UT)
low pulse on the output, followed by the high time defined in the protocol (nominal values,
may vary by tolerance of internal RC oscillator, not including analog delay of the open
drain output and influence by external circuitry, unit time programming see

of the following parts, depicted in
• A trigger pulse by the master, which initiates the data transmission
• A synchronization period of 56 UT (in parallel, a new sample is calculated)
• A status nibble of 12-27 UT
• Between 3 and 6 data nibbles of 12-27 UT each (number is programmable, see
• A CRC nibble of 12-27 UT
• An end pulse to terminate the SPC transmission.

The ID register is only actively used in ID selection mode.
