C8051T622/3 and C8051T326/7
25. C2 Interface
C8051T622/3 and C8051T326/7 devices include an on-chip Silicon Labs 2-Wire (C2) debug interface to
allow EPROM programming and in-system debugging with the production part installed in the end applica-
tion. The C2 interface 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.
25.1. C2 Interface Registers
The following describes the C2 registers necessary to perform EPROM programming functions through the
C2 interface. All C2 registers are accessed through the C2 interface as described in the C2 Interface Spec-
ification.
