C8051F300/1/2/3/4/5 devices include an on-chip Silicon Labs 2-Wire (C2) debug interface to allow FLASH pro-
gramming, boundary scan functions, and in-system debugging with the production part installed in the end applica-
tion. The C2 interface operates similar to JTAG, where the three JTAG data signals (TDI, TDO, TMS) are mapped
into one bi-directional C2 data signal (C2D). See the C2 Interface Specification for details on the C2 protocol.
17.1. 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 Spec-
ification.
Bits7-0:
This read-only register returns the 8-bit device ID: 0x04 (C8051F300/1/2/3).
