5.3 The Analog Multiplexer System
The Analog Mux Bus connects to every GPIO pin in ports 0 to 2.
Pins can be 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 can be split
into two sections for simultaneous dual-channel processing. An
additional analog input multiplexer provides a second path to
bring Port 0 pins to the analog array.
Switch control logic enables selected pins to precharge continu-
ously under hardware control. This enables capacitive
measurement for applications such as touch sensing. Other
multiplexer applications include:

When designing capacitive sensing applications, refer to the
latest signal-to-noise signal level requirements application notes,
found at
cation Notes. In general, and unless otherwise noted in the
relevant application notes, the minimum signal-to-noise ratio
(SNR) for CapSense applications is 5:1.

5.4 Additional System Resources
System resources provide additional capability useful in
complete systems. Additional resources include a multiplier,
decimator, low voltage detection, and power on reset. Brief state-
ments describing the merits of each resource follow.

Two multiply accumulates (MACs) provide fast 8-bit multipliers
with 32-bit accumulate, to assist in both general math and
digital filters.
A decimator provides a custom hardware filter for digital signal
processing applications including creation of Delta Sigma
ADCs.
Low Voltage Detection (LVD) interrupts signal the application
of falling voltage levels, while the advanced POR (power on
reset) circuit eliminates the need for a system supervisor.
Digital clock dividers provide three customizable clock
frequencies for use in applications. The clocks can be routed
to both the digital and analog systems. The designer can
generate additional clocks using digital PSoC blocks as clock
dividers.
The I2C module provides 100 and 400 kHz communication over
two wires. Slave, master, and multi-master applications are
supported.
An internal 1.3V reference provides an absolute reference for
the analog system, including ADCs and DACs.
Versatile analog multiplexer system.
