option to be double synchronized. The synchronization clock is
the system clock (see
are synchronized as this is required if the CPU interacts with the
signal or any signal derived from it. Asynchronous inputs have
rare uses. An example of this is a feed through of combinational
PLD logic from input pins to output pins.

There are four more DSI connections to a given I/O port to
implement dynamic output enable control of pins. This
connectivity gives a range of options, from fully ganged 8-bits
controlled by one signal, to up to four individually controlled pins.

The CAN peripheral is a fully functional Controller Area Network
(CAN) supporting communication baud rates up to 1 Mbps. The
CAN controller implements the CAN2.0A and CAN2.0B
specifications as defined in the Bosch specification and
conforms to the ISO-11898-1 standard. The CAN protocol was
originally designed for automotive applications with a focus on a
high level of fault detection. This ensures high communication
reliability at a low cost. Because of its success in automotive
applications, CAN is used as a standard communication protocol
for motion oriented machine control networks (CANOpen) and
factory automation applications (DeviceNet). The CAN controller
features allow the efficient implementation of higher level
protocols without affecting the performance of the
microcontroller CPU. Full configuration support is provided in
PSoC Creator.
