EE[3:0] — EEPROM Mapping Bits
NOSEC — Security Mode Disable Bit
NOCOP — COP System Disable Bit
ROMON — ROM (EPROM) Enable Bit
EEON — EEPROM Enable Bit
When a reset condition is recognized, the internal registers and control bits are
forced to an initial state. Depending on the cause of the reset and the operating
mode, the reset vector can be fetched from any of six possible locations. Refer to
Table
These initial states then control on-chip peripheral systems to force them to known
startup states, as described in the following subsections.
EE[3:0] apply only to MC68HC811E2. Refer to
