LOWSQEN
Write as 0; ignore on read.
Enable the Energy Detect Power-Down mode:
0 = Energy Detect Power-Down is disabled
1 = Energy Detect Power-Down is enabled
Write as 0, ignore on read
The Low_Squelch signal is equal to LOWSQEN AND
EDPWRDOWN.
Low_Squelch = 1 implies a lower threshold
(more sensitive).
Low_Squelch = 0 implies a higher threshold
(less sensitive).
