INTERNAL REGISTERS
The ADM1060 contains a large number of data registers. A brief
description of the principal registers is given below. More
detailed descriptions are given in the relevant sections of this
data sheet.
Address Pointer Register.
This register contains the address
that selects one of the other internal registers. When writing to
the ADM1060, the first byte of data is always a register address,
which is written to the Address Pointer register.
Configuration Registers.
These registers provide control and
configuration for various operating parameters of the
ADM1060.
Polarity Registers.
These registers define the polarity of inputs
to the PLBA.
Mask Registers.
These registers allow masking of individual
inputs to the PLBA and masking of faults in the fault reporting
registers.
