This 6-bit field selects the Flash memory page for Programming and Page Erase
operations. Program Memory Address[16:11] = FPAGE[8:3] = PAGE[5:0].
The Flash Frequency register (see
operations. The 16-bit Flash Frequency register must be written with the system clock
frequency in kHz. The Flash Frequency value is calculated using the following equation:
Flash programming and erasure is not supported for system clock frequencies
below 32 kHz, above 20 MHz, or outside of the valid operating frequency range for
the device. The Flash Frequency register must be loaded with the correct value to
ensure proper program and erase times.
FFREQ—Flash Frequency
This value is used to time flash program and erase operations.
