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

logic AND operation.

Finally, using the result decimal value 'n', issue an ATS38=n to set the register S38 to the new 

desired value. 

 

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.
