Offset:
• FRDY: Ready Interrupt Enable
0: Flash Ready does not generate an interrupt.
1: Flash Ready (to accept a new command) generates an interrupt.
• FWS: Flash Wait State
This field defines the number of wait states for read and write operations:
• FAM: Flash Access Mode
0: 128-bit access in read Mode only, to enhance access speed.
1: 64-bit access in read Mode only, to enhance power consumption.
No Flash read should be done during change of this register.
