the TMPM330, the internal regulator requires at least 700 μs to be stable. The time required to achieve
stable oscillation varies with system. At cold reset, the external reset pin must be kept low for a duration
of time sufficiently long enough for the internal regulator and oscillator to be stable.
The TMPM330 has three reset sources: an external reset pin, WDT and SYSRESETREQ. For reset
The power-on sequence must include the time for the internal regulator and oscillator to be stable. In

Cold Reset
Turn on the power while the RESET pin is fixed to “L”. Release the RESET pin while all the
power supplies are stabilized within operating voltage.
