Table 2-1. IMA2 module pin definitions
Notes:
1: Leave pin 142 floating; the module can turn on automatically when a power
supply exists.
2: Pin 144 can be used as a wake-up as the module enters deep-sleep status. The
default configuration is active high to wake up the LGA module.
3: The VREF voltage will turn off when entering the deep sleep state.
