Note:
The A/D clock source bits (ADCS1:ADCS0)
have had their operation modified.
Register 1 for a new definition of the ADCS1 and
ADCS0 bits.
Figure 1 shows how the T
based upon the selection of the ADCS<1:0> bits
and the source of V
or V
ence (VRH or VRL), then the required T
increased by a factor of eight (see electrical spec-
ification parameter #130A).
The clock source selected by the ADCS<1:0> bits
is divided by eight when an internally generated
reference voltage is used as reference to the A/D
module. This automatically addresses the require-
ment for the T
