Description of Changes
Initial version copied from V01.06,
changed unused Bits in ATDDIEN to read logic 1
Updated Table 12-15 Analog Input Channel Select Coding -
description of internal channels.
Updated register ATDDR (left/right justified result) description
in section 12.3.2.12.1/12-415 and 12.3.2.12.2/12-416 and
added table Table 12-21 to improve feature description.
Fixed typo in Table 12-9- conversion result for 3mV and 10bit
resolution
Corrected Table 12-15 Analog Input Channel Select Coding -
description of internal channels.
Corrected typos to be in-line with SoC level pin naming
conventions for VDDA, VSSA, VRL and VRH.
Removed feature of conversion during STOP and general
wording clean up done in Section 12.4, “Functional
Description
Update of internal only information.
Connectivity Information regarding internal channel_6 added
to Table 12-15.
Fixed typo in bit description field Table 12-14 for bits CD, CC,
CB, CA. Last sentence contained a wrong highest channel
number (it is not AN7 to AN0 instead it is AN11 to AN0).
