Note 1: ADRES register may be read on the following TCY cycle.
2: 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 50 .
3: On the following cycle of the device clock.
