C8051F52x/F53x
21. C2 Interface
C8051F52x/F52xA/F53x/F53xA devices include an on-chip Silicon Laboratories 2-Wire (C2) debug inter-
face to allow Flash programming 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.
21.1. 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.
C2 Register Definition 21.1. C2ADD: C2 Address
C2 Register Definition 21.2. DEVICEID: C2 Device ID
