The FSITX has two muxes connected to the transmitter core, EXTRIG and PINGTRIG. These muxes are used to select external signals as a trigger to start generic frames, and ping frames. The muxes are independently configured for each type of frame. The application can select one trigger source per frame type. Note that the use of these triggers is optional.
The generic frame trigger is configured by setting TX_OPER_CTRL_HI_ALT1_.EXT_TRIG_SEL to the index of the desired trigger. TX_OPER_CTRL_LO_ALT1_.START_MODE must be set to 0x1 for a frame to be transmitted by an external trigger.
The external ping frame trigger is configured by setting TX_PING_CTRL_ALT1_.EXT_TRIG_SEL to the index of the desired trigger. TX_PING_CTRL.EXT_TRIG_EN must also be set to allow the trigger to generate a ping frame.
