Function And Operation; Cold Reset - Toshiba TXZ+ Series Reference Manual

3.2. Function and Operation

This chapter explains about power on, power off, and reset.
Note: Refer to the datasheet "Electrical Characteristics" chapter for the time and voltage of description of the
symbol in a figure.

3.2.1. Cold reset

When turn on a power supply, the stabilization times for the built-in regulator, the built-in Flash memory, and the
built-in high speed oscillator are necessary. The TXZ + family automatically inserts a wait time for the
stabilization of these circuits.
When turning on the power, please make sure that the slope of the power supply voltage rises to the right.
When the power supply voltage drops and rises near POR and PORF detection, it may not operate normally even
if the power supply voltage rises to the guaranteed operating range.
