6.3.2. Microcontroller/USB Interface
Communication to the tuner and configuration is through firmware on a Silicon Laboratories C8051F340 USB
microcontroller. This device translates USB commands via HID interface to I 2 C control words to the tuner.
PB1 resets the microcontroller.
LED's D3–D6 are driven by the microcontroller. The green LED D4 lights when the microcontroller has booted.
The USB connection may be disconnected once the tuner is configured. Tuner settings will persist until reset or the
power is removed.
