5.2.2 32kHz External Clock
An externally supplied 32kHz reference clock on the CLK32K input (DIO9) may be provided to the JN5139. This
would allow the 32kHz system clock to be sourced from a very stable external oscillator module, allowing more
accurate sleep cycle timings. (See section 17.2.3 I/O Characteristics, DIO9 is a 3V tolerant input)
