SPI Pins
The SPI port has a few different pin location options as shown in
. The port location is selectable via the GPIO control
register [0xC006].
High-Speed Serial Interface
EZ-Host provides an HSS interface. The HSS interface is a
programmable serial connection with baud rate from 9600 baud
to 2.0M baud. The HSS interface supports both byte and block
mode operations and also hardware and software handshaking.
Complete control of EZ-Host can be accomplished through this
interface via an extensible API and communication protocol. The
HSS interface can be exposed through GPIO pins or the External
Memory port.

Programmable Pulse/PWM Interface
EZ-Host has four built in PWM output channels. Each channel
provides a programmable timing generator sequence that can be
used to interface to various image sensors or other applications.
The PWM interface is exposed through GPIO pins.
