application rx_per.c
Author: MOTOROLA
Application Note:
RX_per waits for a ZigBee packet to be received.
Then the link quality of the ZigBee packet is measured by reading the link quality register.
A comparison is made between SPEC_POWER L1_POWER, L2_POWER, and L3_POWER.
From this comparison a ACK packet is formed {'A','C','K', x = {0,1,2,3}} where x represents the respective power settings.
After the ACK is sent the RADIO returns to RX forever mode.
