2.1 GPIO: The Basic Pin Behavior
A simplified block diagram of the GPIO module can be found in
the major interfaces of the GPIO module.
The following sections describe in more details the GPIO module behavior.
The pins that can be set as GPIO pins is available in

is switched from its functional mode to GPIO mode. The inactive state is used to

or used to store data when the GPIO module is used in sampling mode. In both
cases up to 4 First In First Out (FIFO) memory buffers are available for one of the
modes.
the DCS bus interface used to convey the MMIO register read and writes issued
by the TM3260 CPU or any other master connected to PNX15xx/952x Series
through the PCI bus interface.

associated with the signal monitoring while the last interrupt line is linked to the
event monitoring.
