Exit K20D50 from LLS mode active mode using UART RX pin to enable LLWU

[joginderrana]

HI,

I am facing a problem in exiting k20d50 controller from the LLS mode to active mode. I did it using external LLWU GPIO pin. But for a certain application I need to enable LLWU mode by pulling the UART RX line active high.

This feature is given in the K20 Sub-Family Reference Manual (page number 67). I am just wondering to know how to activate this mode in MK20DX128VLH5 MCU.  I am using cw-10.5 and is equipped with processor expert.
