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
Document Number: 001-44094 Rev. *J
Eight analog local buses (abus) to route signals between the
different analog blocks
Multiplexers and switches for input and output selection of the
analog blocks

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
