/*
* REGA Alam and Test
* ==================
*
* This bit of code is to implement the REGA test and alarm functions.
* This function sends out a fixed ZVEI tone sequence for testing or alarm purposes.
* Further information: https://www.rega.ch/en/our-missions/sites-and-infrastructure/emergency-radio
*
* There are two REGA ACTIONS: Test and Alarm.
* The Test action sends out a fixed ZVEI tone sequence for testing purposes.
* The Alarm action sends out a fixed ZVEI tone sequence for alarm purposes.
*
* These actions can be assigned to a key in the settings menu.
*
* The Test/Alarm function will perform the following actions:
* - Set the radio to transmit mode
* - Wait 100ms to allow the radio to switch to transmit mode and stabilize the tramsmitter
* - Send out the ZVEI tone sequence
* - Wait 100ms to allow the radio to finish transmitting
* - Set the radio back to receive mode
*
* The ZVEI tone squence for alarm is: 21414
* The ZVEI tone squence for test is: 21301
*
* To save space the two tone sequences are stored as precalculated register values.
* This avoids the need to calculate the register values at runtime.
* They are hardcoded as array of 32bit integers in the rega.h file.

/*
* REGA Alam and Test
* ==================
*
* This function sends out a fixed ZVEI tone sequence for testing or alarm purposes for the Alpine REGA alarm channel.
* Further information: https://www.rega.ch/en/our-missions/sites-and-infrastructure/emergency-radio
*
* There are two REGA ACTIONS: Test and Alarm.
* The Test action sends out a fixed ZVEI tone sequence for testing purposes.
* The Alarm action sends out a fixed ZVEI tone sequence for alarm purposes.
*
* These actions can be assigned to a key in the settings menu.
*
* The Test/Alarm function will perform the following actions:
* - Set the radio configuration to the REGA frequency, CTCSS, FM, full power etc.
* - Start transmitting
* - Wait 100ms to allow the radio to switch to transmit mode and stabilize the transmitter
* - Send out the ZVEI tone sequence
* - Wait 100ms to allow the radio to finish transmitting
* - Set the radio back to receive mode
*
* The REGA frequency is 161.300 Mhz
*
* The ZVEI tone squence for alarm is: 21414
* The ZVEI tone squence for test is: 21301
*
* The two tone sequences are hardcoded in two arrays
