General Description
1.3 Mask Options
The MC68HC05P4A has 13 mask options:
• CLOCK, RC or crystal
• IRQ, edge-sensitive only or edge- and level-sensitive
• SIOP, most significant bit (MSB) or least significant bit (LSB) first
• COP watchdog timer, enable/disable
• Keyscan pullups and interrupts on port A, enable/disable by pin
• STOP instruction
All mask options and the user ROM are programmed on the 01 layer in fabrication.
