BIT NAME

(0 = LSB)

DEFAULT

R/W

FUNCTION

This bit is used to enable/disable the ZC Block.

R/W

0 = disabled, 1 = enabled.

This bit is used to enable/disable the REF1 Block.

REF1

R/W

0 = disabled, 1 = enabled.

This bit is used to enable/disable the REF2 Block.

REF2

R/W

0 = disabled, 1 = enabled.

This bit is used to enable/disable the PA output stage.

When the PA output stage is enabled it functions normally with a

low output impedance, capable of driving heavy loads.

PA_OUT

R/W

When the PA output stage is disabled it is placed into a high

impedance state.

0 = disabled, 1 = enabled.
