Integrator's Note:
The 3.3 V power to the Mini Card can be controlled by the FPGA. By default, the power is always
on, but there is a register setting that turns this power off in sleep modes. The Mini Card 1.5 V
power is always turned off in sleep modes.

Activity on Wireless PAN (Note)
Illuminates when the 3.3 V power to the Mini Card is on. It alerts users to not hot-
plug the Mini Card. By default, Mini Card power stays on when the processor is in
sleep modes.
