Output stage diagnostics
All the outputs voltage are compared with the diagnostic threshold (0.38 Typ · VCC) and this
information is transferred in dedicated fault latches which are cleared when the NCS
reaches the state low. Afterward the latch stores the status bit and the first reading after the
error might be wrong. The second one is considered right.
The next
into the dedicated registers.
When NCS is low the data contained in the shift register are transferred to SDO output every
CLK rising edge.
