10. Maximum is highest voltage that POR is possible.
11. These values assume the LVI is operating in 5-V mode (i.e. LVI5OR3 bit is set to 1).
12. These values assume the LVI is operating in 5-V mode (i.e. LVI5OR3 bit is set to 1).
13. These values assume the LVI is operating in 5-V mode (i.e. LVI5OR3 bit is set to 1).
14. PTA0–PTA4 pullup resistors are for interrupts only and are only enabled when the keyboard is in use.
1. V
2. Typical values reflect average measurements at midpoint of voltage range, 25°C only.
3. Some disturbance of the ADC accuracy is possible during any injection event and is dependent on board layout and power
4. Run (operating) I
5. All measurements taken with LVI enabled.
6. Wait I
7. Stop I
8. Pullups and pulldowns are disabled.
9. Maximum is highest voltage that power-on reset (POR) is guaranteed.
