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.
