a. VIO is specified with all pins idle (not switching) and not driving any loads.
b. WL_REG_ON and BT_REG_ON are both low. All supplies are present.
c. Idle, not associated, or inter-beacon.
d. Beacon Interval = 102.4 ms. Beacon duration = 1 ms @ 1 Mbps. Average current over 3× DTIM intervals.
e. Duty cycle is 100%. Carrier sense (CS) detect/packet receive.
f. Measured using packet engine test mode.
g. Carrier sense (CCA) when no carrier present.
h. Duty cycle is 100%.
