20. C2 Interface
C8051F31x devices include an on-chip Silicon Labs 2-Wire (C2) debug interface to allow Flash program-
ming, boundary scan functions, and in-system debugging with the production part installed in the end
application. The C2 interface uses a clock signal (C2CK) and a bi-directional C2 data signal (C2D) to trans-
fer information between the device and a host system. See the C2 Interface Specification for details on the
C2 protocol.
20.1. C2 Interface Registers
The following describes the C2 registers necessary to perform Flash programming and boundary scan
functions through the C2 interface. All C2 registers are accessed through the C2 interface as described in
the C2 Interface Specification.
Bits7-0:
This read-only register returns the 8-bit device ID: 0x09 (C8051F310/1/2/3/4/5).
