The Flash Controller provides proper signals and timing for the Byte Programming, Page
Erase, and Mass Erase operations in Flash memory. The Flash Controller contains a
protection mechanism, through the Flash Control Register (FCTL) to prevent accidental
programming or erasure. The following sections provide details about the Lock, Unlock,
Sector Protect, Byte Programming, Page Erase, and Mass Erase operations:

Before performing a program or erase operation on Flash memory, you must first
configure the Flash Frequency High and Low Byte registers. The Flash Frequency
registers allow programming and erasure of Flash with system clock frequencies ranging
from 32 kHz through 20 MHz (valid range is limited to device operating frequencies).
The Flash Frequency High and Low Byte registers combine to form a 16-bit value,
FFREQ, to control the timing of Flash program and erase operations. The 16-bit Flash
Frequency value must contain the system clock frequency in kHz. This value is calculated
using the following equation:
Program Memory

FE00h–FE3Fh
FE40h–FE53h
FE54h–FFFFh
