| REGx_KEY | Region key, bits [31:0] This register must be written before the region corresponding REG_EN bit in OTFDEC_RxCFGR is set. Reading this register returns a zero value. Writing to this register is discarded if performed while the region CONFIGLOCK or KEYLOCK bit is set in the OTFDEC_RxCFGR. Note: When application successfully changes MODE bits in OTFDEC_RxCFGR and OTFDEC_RxKEYR, and associated KEYCRC are erased. |
