Note 1:
The time of the A/D clock period is dependent on the device frequency and the TAD clock divider.
2:
ADRES registers may be read on the following TCY cycle.
3:
The time for the holding capacitor to acquire the “New” input voltage when the voltage changes full scale after the con-
version (VDD to VSS or VSS to VDD). The source impedance (RS) on the input channels is 50W.
4:
On the following cycle of the device clock.
