B-3
bits in the S-register simultaneously, the second command lets you change bit 'm' without affecting
other bits in this S-register. When using ATS
r
=
n
, you need to do a conversion to or from the binary
number to find out which bits you manipulate.
For example, if you want to set S38 bit 3 to 1 for a specific application, you may either use the
straight-forward command ATS38b3=1 or use the following ATS38=
n
command, as explained in
the following example:
1.
Read the value from S38 using ATS38?
NOTE:
The values used in the example below differ from the actual
values in the S-register and are used for demonstration purposes only.
2.
Convert it to binary, using the following weight table:
