The PIC32CX-BZ6 family is based on an ARM® Cortex® M4F
core with different CPU clock settings. The Flash Controller (FC) abstracts the Flash topology
to program the internal embedded Flash, while the Device Service Unit (DSU) serves as the
programming interface, using ARM’s two-wire SWD interface. The following table lists CPU clock
of different devices.

Note: The information on the PIC32CX-BZ3 is provided for comparison and reference purposes.
The Device Service Unit (DSU) module on device provides a means to detect debugger
probes. This enables the ARM Debug Access Port (DAP) to have control over multiplexed debug
pads and CPU Reset. Serial Wire Debug (SWD) is a two-wire protocol for accessing the ARM debug
interface (Refer ARM® Debug Interface Specification v5). The Flash Controller (FC)
which abstracts the Flash topology for programming the embedded single panel Flash. Figure 2-1. DSU Block Diagram
