6 SX9324 has 3 inputs, CS0, CS1 and CS2. Hardware layout
7 defines if the input is
11 + connected to an antenna where it can act as a base
12 (DS - data shield), or measured input (MI).
14 The sensor rotates measurement across 4 phases
15 (PH0, PH1, PH2, PH3), where the inputs are configured
18 By default, during the first phase, [PH0], CS0 is measured,
19 while CS1 and CS2 are used as shields.
20 `cat in_proximity0_setup` returns "MI,DS,DS".
21 [PH1], CS1 is measured, CS0 and CS2 are shield:
22 `cat in_proximity1_setup` returns "DS,MI,DS".
23 [PH2], CS2 is measured, CS0 and CS1 are shield:
24 `cat in_proximity1_setup` returns "DS,DS,MI".
25 [PH3], CS1 and CS2 are measured (combo mode):
26 `cat in_proximity1_setup` returns "DS,MI,MI".
28 Note, these are the chip default. Hardware layout will most
29 likely dictate different output. The entry is read-only.
