Table 14: Bit assignment of parameters of options byte
The logically ORed byte values of the individual bits amount to the value of
the options byte. To change an individual parameter, you have to look at
the bit representing this parameter. After having set the bit on TRUE in
order to activate the corresponding parameter (respectively the desired
function), you have to logically OR the new byte value of the changed bit
with the byte values of the other TRUE bits. For examples of how to
perform such a calculation, see
Examples of calculating the options byte
section on page 63.
The following exemplary step-by-step instructions show how to change the
default options of the
DIL-SWD-32-001
device, in order to allow the
replacement of the device by an universal module.
