REGISTER SET
Most functions of the device 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 the ALU, accumulator registers, data pointers, interrupt vectors and control, and stack
pointer. The peripheral registers define additional functionality that may be included by different products based on
the MAXQ20 architecture. This functionality is broken up into discrete modules so that only the features required
for a given product need to be included. Table 1 shows the DS2790 register set.
