Not all GPIO pads support all these three modes:
• GPIO4 supports all three modes and can be input, output, RF
Transmission Control (Alternate function)
• GPIO5 supports all three modes and can be input, output, RFTX monitor
output (Alternate function)
• GPIO6 supports all three modes and can be input, output, alarm output
(Alternate function)
