Tire Pressure Monitoring Sensor
Description
Defines Sensor Configuration (refer to
and
Table
14)
Defines the number of system clock cycles
(12 MHz RC Oscillator) divided by 8 which is
waited between consecutive measurements.
Note: Only applicable if SensorConfig.2-0
[2POWN2:0] greater than 1 Sample
Pointer to an integer array in RAM to receive the
measurement result
be used as input parameter. Refer to bit
RAWTemp in SensorConfig.
(optional input parameter) Value for hysteresis
(in 1/16kPa) used by the pressure auto-range
selection to determine when to switch from High-
to-Low. It must be specified only if the parameter
SensorConfig.11 is set to 1 (Customer
