PRELIMINARY

DATASHEET

This example configuration is achieved as follows:

Table 92 Listen Mode with SyncAddress Condition Settings

Variable

Effect

IdleMode

1: Sleep mode

FromStart

00: To LowPowerSelection

LowPowerSelection

1: To Idle state

FromIdle

1: To Receive state on T1 interrupt

FromReceive

101: To Sequencer off on SyncAddress interrupt

FromRxTimeout

10: To LowPowerSelection

TTimeoutRxPreamble should be set to just long enough to catch a preamble (depends on PreambleDetectSize and BitRate).

TTimer1 should be set to 64 µs (shortest possible duration).

TTimer2 is set so that TTimer1 + TTimer2 defines the time between two start of reception.

In order to insure packet detection and optimize the receiver power consumption, the received packet Preamble should be

defined so that TPreamble = TTimer2 - TSyncAddress with TSyncAddress = (SyncSize + 1)*8/BitRate.

An example of DIO configuration for this mode is described in the following table:
