SECTION 3 – SYSTEM REGISTER DESCRIPTIONS
Most functions of the DS4830A are controlled by sets of registers. These registers provide a working space for memory
operations as well as configuring and addressing peripheral registers on the device. Registers are divided into two major
types: system registers and peripheral registers. The common register set, also known as the system registers, includes
ALU access and control registers, accumulator registers, data pointers, interrupt vectors and control, and stack pointer.
The peripheral registers define additional functionality and the functionality is broken up into discrete modules.
This section describes the DS4830A’s system registers. Table 3-1 shows the DS4830A system register map. Table 3-2
explains system register bit functions. This is followed by a detailed bit description.
