Self-Test Control Unit (STCU)
• Write the keys into the STCU_ERRK
• Set/clear the STCU_ERR register
where
• Key1 allows to clear the fields that have a value of 1 by writing a 0 to those fields
• Key2 allows to set the fields that have a value of 0 by writing a 1 to those fields
In case of invalid access (wrong or missing key), a transfer error is asserted (it depends on the selected bus
interface) and the writing operation on STCU_ERR register is ignored.
