• Stack
  - 32 levels
• Serial I/O
  - Three channels. These circuits can support both 2- wire and 3-wire 8-bit communication techniques, and can be switched between MSB first and LSB first operation.
  - One of six internally generated serial transfer clock rates can be selected: 12.5, 37.5, 187.5, 281.25, 375, and 450 kHz.
• External interrupts
  - Seven interrupt inputs (pins INT0 through INT5, and the HOLD pin)
These interrupts can be set to switch between rising and falling edges, although the HOLD pin only supports falling edge detection.
• Internal interrupts
  - Seven interrupts; four internal timer interrupts, and three serial I/O interrupts.
