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.
8.1.1 Features
Document Number: 001-55035 Rev. *F
Flexible, configurable analog routing architecture
16 Analog globals (AG) and two analog mux buses
(AMUXBUS) to connect GPIOs and the analog blocks
Each GPIO is connected to one analog global and one analog
mux bus
8 Analog local buses (abus) to route signals between the
different analog blocks
Multiplexers and switches for input and output selection of the
analog blocks
PRELIMINARY
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
PSoC
