CRD5376, as an input from the microcontroller to initiate data transactions on command or from the
MCLK/2 clock to initiate data transactions automatically as soon as they are available from the digital filter.
2.3.2
Included on CRD5376 is an 8051-type microcontroller with integrated hardware SPI and USB interfaces.
This C8051F320 microcontroller is a product of Silicon Laboratories (http://www.silabs.com/). Key fea-
tures of the C8051F320 microcontroller are:
The exact use of the microcontroller features is controlled by embedded firmware.
