PHY_SetTxPower() definition detail requested

[joeygold]

refer to https://github.com/MicrochipTech/atsamr34_long_range_p2p/blob/master/03_customize/README.md#configure-the-application-2

Github documentations shows *Settings for North America: PHY_SetTxPower(20)

However in the commented out example it shows setting od 0xIF

Can we have some clarity please

uint8_t txPower = 0x1F ; PHY_SetTxPower(txPower) ; // Read back and print Tx output power txPower = 255 ;
