When FCU performed, does previously notification become invalid?

Latest Updated:12/18/2013


I have a question about the "Using the Peripheral Clock Notification Command" figure in the ROM (Flash Memory for Code Storage) chapter of the User's Manual: Hardware.
When a tPCKA timeout occurs at the FRDY bit check in the flowchart, the flowchart ends after FCU initialization. In the "Peripheral Clock Notification Register (PCKAR)" section, it is indicated that the peripheral notification register is also initialized by the initialization of FCU. When FCU initialization is performed, does the previously issued peripheral clock notification command become invalid?


When FCU initialization is performed, both the peripheral clock notification register and the issuing of the command become invalid.
If FCU initialization has been performed, please issue the peripheral clock notification command again.
