Description
The IPO frequency is specified to be 5.5296 MHz +/- 4% over the supply
voltage range of 2.7 V to 3.6 V and the temperature range of -40 °C to +105
°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.
The sink current may drop below 1 µA over temperature and supply voltage.
Workaround
An external pull-down resistor will improve the sink current performance.
The temperature sensor absolute error is outside the specification over the full
temperature/voltage range.
Workaround
Recalibrate the sensor at the user application temperature or use the temper-
ature sensor output for relative measurements.
When the timer is not enabled, the TPOL bit does not affect the timer output
when changed.
Workaround
When the timer is not enabled, write the Timer Control Register 1 twice with
the same value. This will cause the correct timer output behavior to occur.
The pull-up devices are specified to source at least 30 µA. In actuality, the pull-
up devices may source as little as 7 µA.
Workaround
If a faster pull-up is required, use an external pull-up resistor.
