25. C2 Interface
C8051F54x devices include an on-chip Silicon Labs 2-Wire (C2) debug interface to allow Flash program-
ming 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 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 perform Flash programming through the C2 inter-
face. All C2 registers are accessed through the C2 interface as described in the C2 Interface Specification.
