APPLICATION NOTE 4052
Quick Reference Guide to the DS1863 Memory Map
Abstract: The DS1863 burst-mode PON controller with integrated monitoring capabilities has programming options to
configure the alarms, warnings, lookup tables, and other functions. This programmability necessitates a large register
memory map. This application note provides an outline of the register map, which is convenient when programming
the device.
Memory Map of the DS1863
features six separate memory tables that are internally organized into eight byte rows (
Figure 1
).
1. The
Lower Memory
is addressed from 00h to 7Fh. It contains alarm and warning thresholds, flags, masks,
several control registers, password entry area (PWE), and the Table Select byte.
2.
Table 01h
primarily contains user EEPROM (with PW1 level access) and some alarm and warning status bytes.
3.
Table 02h
is a multifunction space that contains configuration registers, scaling and offset values, passwords,
interrupt registers, and miscellaneous control bytes.
4.
Table 03h
is strictly user EEPROM that is protected by a PW2-level password.
5.
Table 04h
contains a temperature-indexed lookup table (LUT) for controlling the modulation voltage. The
modulation LUT can be programmed in 2°C increments over the -40°C to +102°C range. Access to this register
is protected by a PW2-level password.
6.
Table 05h
contains another LUT, which allows the APC set point to change as a function of temperature to
compensate for Tracking Error (TE). This TE LUT has 36 entries that determine the APC setting in 4°C windows
between -40°C to +100°C. Access to this register is protected by a PW2-level password.
