The Flash Frequency High and Low Byte registers, shown in Tables 76 and 77, combine
to form a 16-bit value, FFREQ, to control timing for Flash program and erase operations.
The 16-bit binary Flash frequency value must contain the system clock frequency (in kHz)
and is calculated using the following equation:
FFREQ[15:0]
Flash programming and erasure is not supported for system clock frequencies below
10 kHz or above 20 MHz. The Flash Frequency High and Low Byte registers must be
loaded with the correct value to ensure proper operation of the device.
