[1] P = power supply; G = ground; I = input, O = output; I/O = input/output.
[2] JTAG programming mode: must be left floating high during reset to avoid entering JTAG programming mode.
[3] UART programming mode: leave pin floating high during reset to avoid entering UART programming mode or hold it low to program
[4] Not available on the JN5169-001-M06-2 since they are used to control the front-end module.
[5] Multi-function: DIO12/PWM2/CTS0/JTAG_TCK/ADO/SPISMOSI.
[6] Multi-function: DIO13/PWM3/RTS0/JTAG_TMS/ADE/SPISMISO.
[7] Multi-function: DIO14/SIF_CLK/TXD0/TXD1/JTAG_TDO/SPISEL1/SPISSEL.
[8] Multi-function: DIO15/SIF_D/RXD0/RXD1/JTAG_TDI/SPISEL2/SPISCLK.
