19.3.1
DSADMR controls the biasing circuit and selects a clock for the ∆Σ A/D converter. DSADMR
can be read by the CPU at any time, but must be written to while the ∆Σ A/D converter is in the
module stop state.

Biasing Circuit Control
Controls whether the biasing circuit is stopped or runs.
0: Biasing circuit is stopped.
1: Biasing circuit runs.
Reserved
These bits are always read as 0. The write value should
always be 0.
∆Σ A/D Converter Clock Select
These bits select the frequency of the ∆Σ A/D converter
clock (Aφ). The values shown below for each setting are
frequency multipliers for the input clock. Set these bits so
that Aφ is approximately 25 MHz. See section 23, Clock
Pulse Generator, for details.
