12 / 146 page  2.4.1 Supply, supply monitoring and current consumption All SPI communication, logic and oscillator parameters are working down to VSREG = 3.5 V and parameters are as specified in the respective chapters. • SPI thresholds • Oscillator frequency (delay times correctly elapsed) • Internal register status correctly kept (reset at default values for VS< VPOR) • Reset threshold correctly detected The voltages are referred to ground, and currents are assumed positive, when the current flows into the pin. 6 V < VS < 28 V, 6 V < VSREG < 28 V, TJ = -40°C to 150°C, unless otherwise specified.
