6.2 Introduction
This section describes the electrically erasable programmable read-only
memory (EEPROM). The 1024 bytes available on the
MC68HC908AS60 are physically located in two 512-byte arrays. This
section details the array covering the address range $0800–$09FF. For
information relating to the array covering address range $0600–$07FF,
see Section 7. EEPROM-2.
