of functions work properly, so that designing the oscillation frequency accurately is required. The spec
of
crystal is recommended to be within
fosc: 8 MHz +/-20 ppm
ftemp: 8 MHz +/-40 ppm (-20°C to +65°C)
While RESET of MCU is active, the MCU function stops. Hardware and software initialization sequence
including power supplies control is required, because status of any hardware after the RESET period is
unknown especially horizontal oscillator which is a very basic timing generator of SP operation.
