18.9
The module has three internal power modes. When the
ADON bit is ‘1’, the module is in Active mode; it is fully
powered and functional. When ADON is ‘0’, the module
is in Off mode. The digital and analog portions of the
circuit are disabled for maximum current savings. In
order to return to the Active mode from Off mode, the
user must wait for the ADC circuitry to stabilize.
18.10 A/D Operation During CPU Sleep
18.10.1
When the device enters Sleep mode, all clock sources
to the module are shutdown and stay at logic ‘0’.
If Sleep occurs in the middle of a conversion, the
conversion is aborted. The converter will not continue
with a partially completed conversion on exit from
Sleep mode.
Register contents are not affected by the device
entering or leaving Sleep mode.
The A/D module can operate during Sleep mode if the
A/D clock source is set to RC (ADRC = 1). When the
RC clock source is selected, the A/D module waits one
instruction cycle before starting the conversion. This
allows the SLEEP instruction to be executed, which
eliminates all digital switching noise from the
conversion. When the conversion is complete, the
DONE bit will be set and the result loaded into the
ADCBUF register.

If the A/D interrupt is enabled, the device will wake-up
from Sleep. If the A/D interrupt is not enabled, the A/D
module will then be turned off, although the ADON bit
will remain set.
18.10.2
The ADSIDL bit selects if the module will stop on Idle or
continue on Idle. If ADSIDL = 0, the module will
continue operation on assertion of Idle mode. If
ADSIDL = 1, the module will stop on Idle.
18.11 Effects of a Reset
A device Reset forces all registers to their Reset state.
This forces the A/D module to be turned off, and any
conversion and acquisition sequence is aborted. The
values that are in the ADCBUF registers are not
modified. The A/D result register will contain unknown
data after a Power-on Reset.
18.12 Output Formats
The A/D result is 10 bits wide. The data buffer RAM is
also 10 bits wide. The 10-bit data can be read in one of
four different formats. The FORM<1:0> bits select the
format. Each of the output formats translates to a 16-bit
result on the data bus.
Write data will always be in right justified (integer)
format.
