The Sensor Controller and the System CPU can share digital peripherals in the AUX domain. If this is required, it is recommended to use the hardware semaphores in SMPH to arbitrate access to the peripheral. For the same reason it is recommended that the System CPU and the Sensor Controller leaves the peripherals in reset state after usage. Table 20-21 lists how TI software assigns resources to the semaphores.
