TAL State Machine

The different operating states of the Transceiver are controlled by the TAL state machine.

Functions
tal_trx_status_t	set_trx_state (trx_cmd_t trx_cmd)
	Sets transceiver state. More...
static void	switch_pll_on (void)
	Switches the PLL on. More...

Variables
bool	tal_rx_on_required
	Indicates if the transceiver needs to switch on its receiver by tal_task(), because it could not be switched on due to buffer shortage. More...
tal_state_t	tal_state
	Current state of the TAL state machine. More...
tal_trx_status_t	tal_trx_status
	Current state of the transceiver. More...

tal_trx_status_t set_trx_state

(

trx_cmd_t

trx_cmd

)

Parameters

trx_cmd

needs to be one of the trx commands

Returns
