25. C2 Interface
C8051F350/1/2/3 devices include an on-chip Silicon Labs 2-Wire (C2) debug interface to allow Flash pro-
gramming and in-system debugging with the production part installed in the end application. The C2 inter-
face uses a clock signal (C2CK) and a bi-directional C2 data signal (C2D) to transfer information between
the device and a host system. See the C2 Interface Specification for details on the C2 protocol.
25.1. C2 Interface Registers
The following describes the C2 registers necessary to allow Flash programming and in-system debugging
with the production part installed through the C2 interface. All C2 registers are accessed through the C2
interface as described in the C2 Interface Specification.
