Setting an S-register
To change a setting for an S-register in the current conÞguration, use the command
ATSr=n <Enter>
where r is the register's number and n is a decimal value from 0-255 (unless otherwise
indicated) that speciÞes the setting.
Important If you do not follow an S-register setting with &W, the setting will be
retained only until the next reset or power-off.
ATS13=8&W <Enter>
Sr=n Set S-register value: r is any S-register; n must be a decimal number between 0 and
255.
Sr.b=n Alternative command for setting bit-mapped registers: r is the bit-mapped register,
.b is the bit, n is 0 (off) or 1 (on).
