Preliminary Technical Information
REGISTERS
The AD6426 contains 88 Channel Codec Control Registers, 69
H8 Peripheral Registers mapped into the Channel Codec
address space starting at 8000h. All registers are normally
accessed by the Layer 1 software provided with the
AD20msp425 chipset. The user is not expected to read or
write to any registers other than through the Layer 1 software.
Therefore only a limited description of these registers is given
here to ease the understanding of the functional behavior of
the AD6426. Only registers which can be modified or
monitored by the user under control of the Layer 1 software
are shown. The Channel Codec Control Registers are listed in
Table 1, and the H8 Peripheral Control Registers in Table 3
A description of the Channel Codec Control Register contents
is shown in Table 2, and of the H8 Peripheral Registers in
Table 4.
