Table 99. TSC_SM_2
SM CODE TSC_SM_2
Description Application-level detection of permanent failures of TSC acquisition
Ownership End user
Detailed implementation
This method must detect TSC module permanent failure leading to wrong or missing
acquisition of touch sensing events.
Error reporting Depends on implementation
Fault detection time Depends on implementation
Addressed fault model Permanent
Dependency on Device configuration None
Initialization Depends on implementation
Periodicity Periodic
Test for the diagnostic Not applicable
Multiple-fault protection CPU_SM_0: Periodic core self-test software
Recommendations and known limitations
Due to the strictly application-dependent nature of this solution, no detailed guidelines for
its implementation are given here. As a solution fully based on microcontroller resources is
impossible, it is necessary to leverage on the contribution from other components of the final
system.
3.6.28 HASH processor (HASH)
Table 100. HASH_SM_0
SM CODE HASH_SM_0
Description Periodic read-back of HASH configuration registers
Ownership End user
Detailed implementation
