Flash Controller and Instruction Cache
14.1 Registers (FLC)
The value of this field is used to generate a 1 microsecond width pulse from the system clock source. This pulse is used when performing write or erase operations
on the flash memory. This field should be set to the system clock source frequency in MHz (or as close as possible); for example, if the system clock is running at
24MHz, this field should be set to 24.
