Section 3 Memory Map and Registers

3.1 Overview

This section describes the memory map and registers for the EEPROM module.

3.2 Module Memory Map

A linear EEPROM memory map is shown in Figure 3-1. The HCS12X architecture actually places the EEPROM memory addresses between logical addresses $0800 and $1000 with $0800 to $0BFF representing 1K byte of paged EEPROM memory and $0C00 to $0FFF representing 1K byte of fixed EEPROM memory. The EPROT register, described in section 3.3.5, can be set to protect the upper region in the EEPROM memory from accidental program or erase. The EEPROM addresses covered by this protectable region are shown in the EEPROM memory map. The default protection setting is stored in the EEPROM configuration field as described in Table 3-1.
