11.0 Low Power Modes
(Continued)
The interface between host and LMX9830 is defined as
described in Figure 22.
11.2.2 Disabling the UART transport layer
The Host can disable the UART transport layer by sending
the “Disable Transport Layer” Command. The LMX9830
will empty its buffers, send the confirmation event and dis-
able its UART interface. Afterwards the UART interface will
be reconfigured to wake up on a falling edge of the CTS
pin.
11.2.3 LMX9830 enabling the UART interface
As the Transport Layer can be disabled in any situation the
LMX9830 must first make sure the transport layer is
enabled before sending data to the host. Possible scenar-
ios can be incoming data or incoming link indicators. If the
UART is not enabled the LMX9830 assumes that the Host
is sleeping and waking it up by activating RTS. To be able
to react on that Wake up, the host has to monitor the CTS
pin.
As soon as the host activates its RTS pin, the LMX9830 will
first send a confirmation event and then start to transmit
the events.
11.2.4 Enabling the UART transport layer from the host
If the host needs to send data or commands to the
LMX9830 while the UART Transport Layer is disabled it
must first assume that the LMX9830 is sleeping and wake it
up using its RTS signal.
When the LMX9830 detects the Wake-Up signal it acti-
vates the UART HW and acknowledges the Wake-Up sig-
nal by settings its RTS. Additionally the Wake up will be
confirmed by a confirmation event. When the Host has
received this “Transport Layer Enabled” event, the
LMX9830 is ready to receive commands.
