The Flash Sector Protect register
programmed or erased from user code. The Flash Sector Protect register shares its Regis-
ter File address with the Page Select register. The Flash Sector protect register can be
accessed only after writing the Flash Control register with 5EH.
User code can only write bits in this register to 1 (bits cannot be cleared to 0 by user code).
SECTn—Sector Protect
0 = Sector n can be programmed or erased from user code.
1 = Sector n is protected and cannot be programmed or erased from user code.
* User code can only write bits from 0 to 1.
The Flash Frequency High and Low Byte registers
form a 16-bit value, FFREQ, to control timing for Flash program and erase operations.
The 16-bit Flash Frequency registers must be written with the system clock frequency in
kHz for Program and Erase operations. Calculate the Flash Frequency value using the fol-
lowing equation:
FFREQ[15:0]
Flash programming and erasure is not supported for system clock frequencies be-
low 20 kHz, above 20 MHz, or outside of the valid operating frequency range for
the device. The Flash Frequency High and Low Byte registers must be loaded
with the correct value to insure proper program and erase times.
