• The I
2
C group box allows external I
2
C device to be controlled using one of the DLPC900 I
2
C interfaces.
For example, if an LED driver requires I
2
C communications to enable the LEDs, then a command can
be sent to the LED driver using this interface. When using the I
2
C interfaces, first configure the I
2
C port
using the commands within the I2C Settings and then perform data transfers using the commands
within the I2C Read/Write .
• The Clock A Configuration group box allows the user to enable and control the output frequency of
OCLKA. The clock can be used as a source to some external logic.
• The GPIO Configuration group box allows the user to configure any of the nine available GPIOs.
These GPIOs can be configured as inputs or outputs.
• The Pulse Width Modulate Control group box allows a user to configure any of the four available PWM
outputs.
NOTE: GPIO_00 – GPIO_03 are shared with the four PWM outputs.
