On Power-on Reset (POR), or any Reset, the Configu-
ration Words are copied from the boot Flash memory to
their corresponding Configuration registers. A Configu-
ration bit can only be programmed = 0 (unprogrammed
state = 1).
During programming, a Configuration Word can be pro-
grammed a maximum of two times before a page erase
must be performed.
After programming the Configuration Words, the device
must be reset to ensure that the Configuration registers
are reloaded with the new programmed data.
These configuration words determine the oscillator
source. If using the 2-wire Enhanced ICSP mode the
configuration words are ignored and the device will
always use the FRC. In 4-wire mode this is not the case.
If an oscillator source is selected by the configuration
words that is not present on the part after reset, the pro-
grammer will not be able to perform flash operations on
the device after it is reset. See the “Special Features”
chapter in the specific device data sheet for details
regarding oscillator selection using the configuration
words.
18.1.1
CONFIGURATION REGISTER
PROTECTION
To prevent inadvertent Configuration bit changes dur-
ing code execution, all programmable Configuration
bits are write-once. After a bit is initially programmed
during a power cycle, it cannot be written to again.
Changing a device configuration requires changing the
Configuration data in the boot Flash memory, and
cycling power to the device.
To ensure integrity of the 128-bit data, a comparison is
made between each Configuration bit and its stored
complement continuously. If a mismatch is detected, a
Configuration Mismatch Reset is generated, which
causes a device Reset.
