TABLE 5-38: REGISTER 17 - MODE CONTROL/STATUS
Address Name Description Mode Default
17.15:14 Reserved Write as 0; ignore on read. RW 0
17.13 EDPWRDOWN Enable the Energy Detect Power-Down mode:
0 = Energy Detect Power-Down is disabled
1 = Energy Detect Power-Down is enabled
RW 0
17.12 Reserved Write as 0, ignore on read RW 0
17.11 LOWSQEN 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).
