5.1 Memory Register Description
The FDL01TU modem contains 28 memory registers which are used to control and store
communication parameters and operation mode settings. After rewriting new register
settings, the power must be cycled, a hardware reset asserted, or a software RST
command is issued to validate the new settings.
The following table briefly lists each register, register function and default value:
