The Analog System
The Analog System is composed of six configurable blocks,
comprised of an opamp circuit allowing the creation of complex
analog signal flows. Analog peripherals are very flexible and are
customized to support specific application requirements.
enCoRe III analog function supports the Analog-to-digital
converters (with 6 to 14-bit resolution, selectable as Incremental,
and Delta Sigma) and programmable threshold comparator).

enCoRe III analog function supports the Analog-to-digital
converters (with 6 to 14-bit resolution, selectable as Incremental,
and Delta Sigma) and programmable threshold comparator).
Analog blocks are arranged in two columns of three, with each
column comprising one CT (Continuous Time - AC B00 or AC
B01) and two SC (Switched Capacitor - ASC10 and ASD20 or
ASD11 and ASC21) blocks, as shown in

The Analog Multiplexer System
The Analog Mux Bus can connect to every GPIO pin in ports 0–5.
Pins which are connected to the bus individually or in any combi-
nation. The bus also connects to the analog system for analysis
with comparators and analog-to-digital converters. It is split into
two sections for simultaneous dual-channel processing. An
additional 8:1 analog input multiplexer provides a second path to
bring Port 0 pins to the analog array.
