/* function: llwu_configure
description: Set up the LLWU for wakeup the MCU from LLS and VLLSx modes
from the selected pin or module.
inputs:
pin_en - unsigned integer, bit position indicates the pin is enabled.
More than one bit can be set to enable more than one pin at a time.
rise_fall - 0x00 = External input disabled as wakeup
0x01 - External input enabled as rising edge detection
0x02 - External input enabled as falling edge detection
0x03 - External input enablge as any edge detection
module_en - unsigned char, bit position indicates the module is enabled.
More than one bit can be set to enabled more than one module
for example: if bit 0 and 1 need to be enabled as rising edge detect call this routine with
pin_en = 0x0003 and rise_fall = 0x02
Note: to set up one set of pins for rising and another for falling, 2 calls to this
function are required, 1st for rising then the second for falling.
