Option Bit Configuration by Reset
Programmable Flash option bits allow user configuration of certain aspects of Z8
Encore!
program memory and read during reset. The features available for control through the
Flash option bits are:
•
•
•
•
•
•
•
Each time the Flash option bits are programmed or erased, the device must be reset for the
change to be effective. During any Reset operation (system reset, or Stop Mode
Recovery), the Flash option bits are automatically read from the Flash program memory
and written to option configuration registers. The option configuration registers, control
the operation of the devices within the Z8 Encore! F0830 Series. Option bit control is
established before the device exits reset and the eZ8 CPU begins code execution. The
option configuration registers are not part of the register file and are not accessible for read
or write access.
Watchdog Timer time-out response selection–interrupt or system reset.
Watchdog Timer enabled at reset.
The ability to prevent unwanted read access to user code in program memory.
The ability to prevent accidental programming and erasure of all or a portion of the user
code in program memory.
Voltage Brownout configuration always enabled or disabled during STOP mode to reduce
STOP mode power consumption.
OSCILLATOR mode selection for high, medium, and low power crystal oscillators, or ex-
ternal RC oscillator.
Factory trimming information for the Internal Precision Oscillator and VBO voltage.
