• Programmable mask options
– Oscillator selection: RC oscillator or crystal/other clock source
– Oscillator operational mode: normal high-frequency operation enabled or
32-KHz operation enabled
– Port 0: 0–3 pull-ups
– Port 0: 4–7 pull-ups
– Port 2: 0–7 pull-ups
– Port 3: pull-ups
– Port 0: 0–3 mouse mode: normal mode (.5V_DD input threshold) versus
mouse mode (.4V_DD input threshold)
Note: The mask option pull-up transistor has a typical equivalent
resistance of 200 K±50% at V_CC=3 V and 450 K±50% at
V_CC=2 V.
