Caution:
Flash Operation Timing Using the Flash Frequency Registers
Flash Code Protection Against External Access
Flash Code Protection Against Accidental Program and
Erasure
Before performing either a program or erase operation on Flash memory, you must first
configure the Flash Frequency High and Low Byte registers. The Flash Frequency regis-
ters allow programming and erasing of the Flash with system clock frequencies ranging
from 32 kHz (32768 Hz) through 20 MHz.
The Flash Frequency High and Low Byte registers 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). This value is calcu-
lated using the following equation:
The user code contained within the Flash memory can be protected against external access
by the on-chip debugger. Programming the FRP Flash option bit prevents reading of the
user code with the On-Chip Debugger. See the
the
The Z8 Encore! XP F082A Series provides several levels of protection against accidental
program and erasure of the Flash memory contents. This protection is provided by a com-
bination of the Flash option bits, the register locking mechanism, the page select redun-
dancy and the sector level protection control of the Flash Controller.
Flash Code Protection Using the Flash Option Bits
The FRP and FWP Flash option bits combine to provide three levels of Flash Program
Memory protection, as shown in Table 79. See the
for more information.
FFREQ[15:0]
Flash programming and erasure are not supported for system clock frequencies below
32 kHz (32768 Hz) or above 20 MHz. The Flash Frequency High and Low Byte registers
must be loaded with the correct value to ensure operation of the Z8 Encore! XP F082A
Series devices.
