TIP
- Data in the above tables map to slaves with addresses 1A-31A and 1B-31B. A '—' character
indicates no mapping.
- Each bit position in Tables 4.2-4.5 is either '1' or '0', depending on the state of its corresponding
slave. A bit in the LPS, LAS, LDS and LPF is '1' if the corresponding slave is present, active,
detected or experiencing peripheral fault respectively.
- All areas in Tables 4.2-4.5 are read-only areas accessible by a program.
