To set bit 3 to 0 (binary), you must invert the value using a logic NOT operation and then do a
logic AND operation.

5. Finally, using the result decimal value 'n', issue an ATS38=n to set the register S38 to the new
desired value.
S-Register Descriptions
In most bit-mapped S-registers, the default bit value is 0 (which is the normal situation), only the
non-default situation is described. Some reserved bits are for factory use and the user should not
change them.
Values followed by an asterisk (*) are the factory set default settings.
The following sections provide a description for each S-register.
