Modes of Operation
b
This is the normal transmitting and receiving mode. The voltage regulator is in Normal mode and
can source 50 mA. The undervoltage detection is activated. The watchdog needs a trigger
signal from PTRIG or NTRIG to avoid resets at NRES.
A falling edge at EN while TXD is high switches the IC into Silent mode. The TXD signal has to
be logic high during the Mode Select window (see
two independent outputs can be used, or two outputs from the same microcontroller port; in the
second case, the mode change is only one command. In Silent mode, the transmission path is
disabled. Supply current from V
