peculiar use, so the logic level of each of them
must be considered.
Some special configuration data, that needs to be
load at the start-up and not further changed, are
stored in Option Bytes. These are loaded only
during the device programming phase. See Table
3.3 and Section 4 for a detailed description of the
Option Bytes.
The Configuration Registers are readable and
writable; the addresses refer to the same register
both in read and in write. In order to access the
Configuration Register the user can work in
several
modes
by
utilizing
instructions:

the

Program/Data Memory location, allowing the
configuration data to be taken from a table.
I
LDCNF: loads the
specified with the contents of the Configuration
Register indicated, allowing for the inspection of
the configuration of the device (permitting safe
run-time modifications).
In order to simplify theconcept, a mnemonic name
is assigned to each register. The same name is
used in Visual FIVE development tools. The list of
the Configuration Registers is shown in Table 3.4.
