Additional System Resources
System resources provide additional capability, such as
configurable USB and I
communication interface, three 16-bit programmable timers, and
various system resets supported by the M8C.
These system resources provide additional capability useful to
complete systems. Additional resources include low voltage
detection and power on reset. The merits of each system
resource are listed here:

The I
kHz communication over two wires. SPI communication over
three or four wires runs at speeds of 46.9 kHz to 3 MHz (lower
for a slower system clock).
The I
already low power consumption by eliminating the need for
CPU intervention until a packet addressed to the target device
is received.
The I
buffer to the external I
protocol, the master controls the read and write pointers into
the RAM. When this method is enabled, the slave does not stall
the bus when receiving data bytes in active mode. For usage
details, refer to the application note
Operation -
Low-voltage detection (LVD) interrupts can signal the
application of falling voltage levels, while the advanced power-
on-reset (POR) circuit eliminates the need for a system
supervisor.
An internal reference provides an absolute reference for
capacitive sensing.
A register-controlled bypass mode allows the user to disable
the LDO regulator.

Getting Started
The quickest way to understand PSoC silicon is to read this
datasheet and then use the PSoC Designer Integrated
Development Environment (IDE). This datasheet is an overview
of the PSoC integrated circuit and presents specific pin, register,
and electrical specifications.
For in depth information, along with detailed programming
details, see the
CY8C20x36A/46A/66A/96A PSoC devices.
For up-to-date ordering, packaging, and electrical specification
information, see the latest PSoC device datasheets on the web
at www.cypress.com/psoc.
