The PSoC Creator software program provides a user friendly
interface to configure the analog connections between the GPIO
and various analog resources and also connections from one
analog resource to another. PSoC Creator also provides
component libraries that allow you to configure the various
analog blocks to perform application specific functions. The tool
also generates API interface libraries that allow you to write
firmware that allows the communication between the analog
peripheral and CPU/Memory.
8.1 Analog Routing
The CY8C38 family of devices has a flexible analog routing
architecture that provides the capability to connect GPIOs and
different analog blocks, and also route signals between different
analog blocks. One of the strong points of this flexible routing
architecture is that it allows dynamic routing of input and output
connections to the different analog blocks.

8.1.2 Functional Description
Analog globals (AGs) and analog mux buses (AMUXBUS)
provide analog connectivity between GPIOs and the various
analog blocks. There are 16 AGs in the CY8C38 family. The
analog routing architecture is divided into four quadrants as
shown in
(AGL[0..3], AGL[4..7], AGR[0..3], AGR[4..7]). Each GPIO is
connected to the corresponding AG through an analog switch.
The analog mux bus is a shared routing resource that connects
to every GPIO through an analog switch. There are two
AMUXBUS routes in CY8C38, one in the left half (AMUXBUSL)
and one in the right half (AMUXBUSR), as shown in
CMP
Each GPIO is connected to one analog global and one analog
mux bus
