Analog local buses (abus) are routing resources located within
the analog subsystem and are used to route signals between
different analog blocks. There are eight abus routes in CY8C38,
four in the left half (abusl [0:3]) and four in the right half (abusr
[0:3]) as shown in
globals and analog mux buses from being used for
interconnecting the analog blocks.

Multiplexers and switches exist on the various buses to direct
signals into and out of the analog blocks. A multiplexer can have
only one connection on at a time, whereas a switch can have
multiple connections on simultaneously. In
multiplexers are indicated by grayed ovals and switches are
indicated by transparent ovals.
