- Can be used for either input or output
- Voltage handling capability (input and output):
15 V maximum (For open-drain specification ports)
- Output current: 20 mA maximum sink current (Capable of directly driving an LED.) I/O port options to match application requirements:
- Open-drain output and pull-up resistor specification: Can be specified for all ports in bit units.
- Output level at reset specification: Either a high or low level can be specified for ports C and D in 4-bit units each.
• Interrupts Timer overflow vector interrupt (can also be tested by CPU instructions) INT pin or serial I/O full/empty vector interrupt (can also be tested by CPU instructions)
• Stack levels: 4 levels (also used by interrupts)
• Timers: 8-bit programmable timer with 4-bit prescaler
• Clock oscillator options to match application requirements: Oscillator circuit option:
- Two-pin RC oscillator (N and L versions) Two-pin ceramic oscillator or single external clock input pin (N, F, and L versions)
- Divider circuit option: No divider, built-in divideby- three circuit, built-in divide-by-four circuit (N and L versions)
• Continuous square-wave output with a period 64 times the cycle time.
