27.9
27.9.1
When the device enters any Sleep mode, the CTMU
module current source is always disabled. If the CTMU
is performing an operation that depends on the current
source when Sleep mode is invoked, the operation may
not
measurements may return erroneous values.
27.9.2
The behavior of the CTMU in Idle mode is determined
by the CTMUSIDL bit (CTMUCONH<5>). If CTMUSIDL
is cleared, the module will continue to operate in Idle
mode. If CTMUSIDL is set, the module’s current source
is disabled when the device enters Idle mode. In this
case, if the module is performing an operation when
Idle mode is invoked, the results will be similar to those
with Sleep mode.

27.10 Effects of a Reset on CTMU
Upon Reset, all registers of the CTMU are cleared. This
disables the CTMU module, turns off its current source
and returns all configuration options to their default set-
tings. The module needs to be re-initialized following
any Reset.
If the CTMU is in the process of taking a measurement
at the time of Reset, the measurement will be lost. A
partial charge may exist on the circuit that was being
measured, which should be properly discharged before
the CTMU makes subsequent attempts to make a
measurement. The circuit is discharged by setting and
clearing the IDISSEN bit (CTMUCONH<1>) while the
A/D Converter is connected to the appropriate channel.
