S Registers
All bit-mapped registers are read-only. The appropriate AT command which controls the relevant bits in the S
register should be used to change the value.
The factory default values are stored in ROM and are loaded into the active configuration at powerup or by the
ATZ
n
command. In addition, the designated default profile can be changed by entering the &Y
n
command where n
is one of the two possible user profiles.
All of the factory default values may be loaded at any time by entering the &F command.
