Figure 3: Receiver Acquisition Bit Function Timing
Where: i is a delay allowing pins function to change to signal the HOST controller that a RF caused wakeup occurred.
It can be controlled by Reg 0x0E (IRQ Delay).
k (set by Reg 0x0B) is a delay allowing signal levels
to settle before sampling RSSI.
The TX/RX pin can be programmed to perform one of these
functions by writing to the AMIS-52000 internal registers.

Comments
Do not output Sniff on TX/RX pin
Output Sniff comparator results on TX/RX
TX/RX pin is normal operation (DATA)
RC osc. clock is output on the TX/RX pin
TX will output RF energy when TX/RX high
TX will output RF energy when TX/RX low
RX is a high level when RF energy is received
RX is a low level when RF energy is received
Delay from TX/RX line signals a wakeup event
to when the line returns to its normal function
