Description
When the IPO is enabled, the product specification gives a typical current
consumption of 300 µA. The consumption for these date codes is typically 1.5
mA.
Workaround
None.
Open drain output configuration set by Port A-D Output Control sub registers
is possible only for Port A pins. It is not possible to configure Port B, C, D pins
for open drain output.
Workaround
None. Use Port A pins for open drain output.
For 20-pin devices, external Vref is not an option on pin PC2.
Workaround
None.
are found in the pre-production Z8 Encore! XP
Description
The IPO frequency is specified to be 5.5296 MHz +/- 4% over the supply
°C. Actual silicon performance is +/-4% only over a supply voltage range of
3.15 V to 3.45 V and a temperature range of 0 °C to +70 °C.
Workaround
If the application requires better than +/-4% oscillator accuracy, the voltage
and temperature must be controlled such that they remain within the ranges
given above.
voltage range of 2.7 V to 3.6 V and the temperature range of -40 °C to +105
