Examples of calculating the options byte
Individual parameters of the
Options
element (i. e. the device options) can
only be configured by entering a single hexadecimal options byte.
The logically ORed byte values of the individual bits representing the
configuration parameters 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” (i. e. “add up”) the new byte value of the changed bit with the
byte values of the other TRUE bits. Please note that each active bit (i. e.
each bit set TRUE) has a different byte value. The assignment of
parameters to bits and their byte values are shown in table
Bit assignment
of parameters of options byte
on page 60. Because all bits set to FALSE
have the byte value 0, you can ignore all FALSE bits in the addition.
