ICS1531 Data Sheet - Preliminary
Chapter 6 Register Set
Chapter 6 Register Set
The tables in this chapter detail the functionality of the bits in the ICS1531 Register Set. The tables include
the register locations, the bit positions, names, and definitions, along with their read/write access, reset
values, and any special functions or capabilities.
6.1 Reserved Bits
The ICS1531 has a number of reserved bits throughout the Register Set. These bits provide enhanced test
functions (intended for use only by ICS manufacturing) and calibration functions (intended for use in
production environments).
Important: The customer must not change the value of reserved bits. If the customer changes the default
values of these reserved bits, normal operation of the ICS1531 can be affected.
6.2 Register Set Conventions
Register Set conventions include the following:
• Bits are listed in the order of most-significant bit (MSB) to least-significant bit (LSB).
• Unless otherwise indicated, bit settings are listed in terms of digital (and not hexadecimal) values.
• When a bit definition includes word(s) in parentheses, the word in parenthesis is not part of the bit name,
but is given to explain the origin of the bit’s name.
6.3 Register Set Abbreviations and Acronyms
Table 6-1 lists and defines abbreviations and acronyms used specifically in this chapter. (Table 1-1 lists
other abbreviations and acronyms used throughout this data sheet.)
