4. Module: 10-Bit Analog-to-Digital
Converter
When the AD clock source is selected as 2 TOSC or
RC (when ADCS2:ADCS0 = 000 or x11), in
extremely rare cases, the EIL (Integral Linearity
Error) and E
DL (Differential Linearity Error) may
exceed the data sheet specification at codes 511
and 512 only.
Work around
Select the AD clock source as 4 TOSC, 8 TOSC,
16 T
OSC, 32 TOSC or 64 TOSC and avoid selecting
2T
OSC or RC.
