35. C2 Interface
C8051F70x/71x 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 operates using only two pins: a bi-directional data signal (C2D), and a clock input (C2CK). See the C2
Interface Specification for details on the C2 protocol.
35.1. C2 Interface Registers
The following describes the C2 registers necessary to perform Flash programming functions through the
C2 interface. All C2 registers are accessed through the C2 interface as described in the C2 Interface Spec-
ification.
