SECTION 3: SYSTEM REGISTER DESCRIPTIONS
Most MAX31782 functions are controlled by sets of registers . These registers provide a working space for memory oper-
ations 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 MAX31782’s system registers .
Table 3-1 shows the MAX31782 system register map .
Table 3-2 explains system register bit functions . This is followed by a detailed bit description .
