The Device Type Register

Addressing Mode. Bits 13 and 12 indicate the addressing mode used by the device:

0 0 A16/A24 address mode

0 1 A16/A32 address mode

1 0 RESERVED

1 1 A16 address mode

The Agilent E1446 amplifier uses the A16 address mode.

Manufacturer ID. Bits 11 through 0 identify the manufacturer of the device. Agilent Technologie’s ID number is 4095, which corresponds to bits 11 - 0 being set to “1".

Given the device classification, addressing space, and manufacturer of the Agilent E1446, reading the ID register returns FFFF16.

The Device Type register contains a model code which identifies the device.
