General Description
General Release Specification
MC68HC705E5 — Rev. 1.0
General Description
1.4 Mask Options
The M68HC705E5 has these four mask options which are handled with
five EPROM bits (MOR).
1. STOP instruction (enable/disable)
2. IRQ (edge-sensitive only or edge- and level-sensitive)
3. COP watchdog timer (enable/disable)
4. CPI Rate (1 second, 0.5 second, or 0.25 second)
ROM versions of this device will have these options programmed by the
factory. Refer to 13.5 Mask Option Register for additional information
.
NOTE:
A line over a signal name indicates an active low signal. For example,
RESET is active low.
