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. If the

module is performing an operation when Idle mode is
invoked, in this case, 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.
