4.1.6 PWM
Two PWM outputs are available on the GPIO/Automation Extension Connector. Please note that the PWM1 is
also present on the Video Extension Connector.
4.1.7 SPI
Two Serial Peripheral Interfaces are available on the connector. The CSPI1 interface is shared with the I2C1
and provides two slave select signals, the CSPI is shared with the SD-card interface, and provides only a single
slave select signal.
4.1.8 SSI
This interface can be used as alternate digital audio channel and is connected to the AUD4 interface of the
i.MX51.
4.1.9 UART
The signals of the UART2 and UART3 are available on the extension connector for the connection of a variety
of peripheral devices.
4.1.10 Power Supplies
The GPIO / Automation Extension Connector provides seven different supply voltages. They can be used on a
custom extension board. Some supply voltages are generated by the MC13892 and can be set to different
values. They must be set and enabled first, by configuring the companion IC. The following table shows the
maximum supply current for each voltage domain.
