MC Flash Mode Register
Register Name:
Access Type:
Offset:
• FRDY: Flash Ready Interrupt Enable
0 = Flash Ready does not generate an interrupt.
1 = Flash Ready generates an interrupt.
• LOCKE: Lock Error Interrupt Enable
0 = Lock Error does not generate an interrupt.
1 = Lock Error generates an interrupt.
• PROGE: Programming Error Interrupt Enable
0 = Programming Error does not generate an interrupt.
1 = Programming Error generates an interrupt.
• NEBP: No Erase Before Programming
0 = A page erase is performed before programming.
1 = No erase is performed before programming.
• FWS: Flash Wait State
This field defines the number of wait states for read and write operations:
• FMCN: Flash Microsecond Cycle Number
This field defines the number of Master Clock cycles in 1 microsecond.
Warning: The value 0 is only allowed for a master clock period superior to 30 microseconds.
Warning: In order to guarantee valid operations on the Flash memory, the field Flash Microsecond Cycle Number (FMCN)
must be correctly programmed.
