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 ATSr=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:
Bit Binary value Decimal value Hexadecimal value
0 00000001 1 $01
1 00000010 2 $02
2 00000100 4 $04
3 00001000 8 $08
4 00010000 16 $10
5 00100000 32 $20
6 01000000 64 $40
7 10000000 128 $80
3. To set bit 3 to 1 (binary), do a logic OR operation with the value.
