Electrical characteristics

1. Not 100% tested, guaranteed by design characterization.
2. This specification is not valid for outputs which are switched to open drain mode. In this case the respective output will float
3. Port 5 leakage values are granted for not selected A/D Converter channel. One channels is always selected (by default,
4. The leakage of P2.0 is higher than other pins due to the additional logic (pass gates active only in specific test modes)
5. Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the
6. This specification is only valid during Reset, or during Hold- or Adapt-mode. Port 6 pins are only affected, if they are used
7. The maximum current may be drawn while the respective signal line remains inactive.
8. The minimum current must be drawn in order to drive the respective signal line active.
9. The power supply current is a function of the operating frequency (f
10. The Idle mode supply current is a function of the operating frequency (f
11. This parameter is tested including leakage currents. All inputs (including pins configured as inputs) at 0 V to 0.1 V or at V

doing the following:
– Fetching code from IRAM and XRAM1, accessing in read and write to both XRAM modules (for ICC1)
– Watchdog Timer is enabled and regularly serviced
– RTC is running with main oscillator clock as reference, generating a tick interrupts every 192 clock cycles
– Four channel of XPWM are running (waves period: 2, 2.5, 3 and 4 CPU clock cycles): no output toggling
– Five General Purpose Timers are running in timer mode with prescaler equal to 8 (T2, T3, T4, T5, T6)
– ADC is in Auto Scan Continuous Conversion mode on all 16 channels of Port5
– All interrupts generated by XPWM, RTC, Timers and ADC are not serviced
