Chapter 10 Stepper Stall Detector (SSDV1)
10.3 Memory Map and Register Definition
This section provides a detailed description of all registers of the stepper stall detector (SSD) block.
10.3.1 Module Memory Map
Table 10-2 gives an overview of all registers in the SSD memory map. The SSD occupies eight bytes in
the memory space. The register address results from the addition of base address and address offset. The
base address is determined at the MCU level and is given in the Device Overview chapter. The address
offset is defined at the block level and is given here.

10.3.2 Register Descriptions
This section describes in detail all the registers and register bits in the SSD block. Each description
includes a standard register diagram with an associated figure number. Details of register bit and field
function follow the register diagrams, in bit order.
