Additional System Resources
System Resources, some of which have been previously listed,
provide additional capability useful to complete systems.
Resources include a multiplier, decimator, switch mode pump,
low voltage detection, and power on reset. Statements describ-
ing the merits of each system resource are presented below.

Analog blocks are provided in columns of three, which includes
one CT (Continuous Time) and two SC (Switched Capacitor)
blocks, as shown in the figure below.

Digital clock dividers provide three customizable clock fre-
quencies for use in applications. The clocks can be routed to
both the digital and analog systems. Additional clocks can be
generated using digital PSoC blocks as clock dividers.
Multiply accumulate (MAC) provides fast 8-bit multiplier with
32-bit accumulate, to assist in general math and digital filters.
The decimator provides a custom hardware filter for digital
signal, processing applications including the creation of Delta
Sigma ADCs.
The I2C module provides 100 and 400 kHz communication
over two wires. Slave, master, and multi-master modes are
all supported.
Low Voltage Detection (LVD) interrupts can signal the appli-
cation of falling voltage levels, while the advanced POR
(Power On Reset) circuit eliminates the need for a system
supervisor.
An internal 1.3 voltage reference provides an absolute refer-
ence for the analog system, including ADCs and DACs.
An integrated switch mode pump (SMP) generates normal
operating voltages from a single 1.2V battery cell, providing a
low cost boost converter.
