Control

AUX_ENA

AUXADC Enable

0 = Disabled

1 = Enabled

Note - this bit is reset to 0 when the OFF power state is

entered.

AUX_CVT_EN

AUXADC Conversion Enable

0 = Disabled

1 = Enabled

In automatic mode, conversions are enabled by setting

this bit.

In manual mode (AUX_RATE = 0), setting this bit will

initiate a conversion; the bit is reset automatically after

each conversion.

AUX_SLPENA

AUXADC SLEEP Enable

0 = Disabled

1 = Controlled by AUX_ENA

5:0

AUX_RATE

[5:0]

00_0000

AUXADC Conversion Rate

0 = Manual

1 = 2 samples/s

2 = 4 samples/s

3 = 6 samples/s

…

31 = 62 samples/s

32 = Reserved

33 = 16 samples/s

34 = 32 samples/s

35 = 48 samples/s

…

63 = 496 samples/s
