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
These initial states then control on-chip peripheral systems to force them
to known startup states, as described in the following subsections.
Refer to
Refer to
Table 5-2. Reset Cause, Reset Vector, and Operating Mode
0 = COP enabled (forces reset on timeout)
1 = COP disabled (does not force reset on timeout)
