Tiny Real-Time Clock/calendar with alarm function and I2C-bus
7.2.1.3 Software reset
A reset is automatically generated at power-on. There is a low probability that some devices will have corruption
of the registers after the automatic power-on reset if the device is powered up with a residual VDD level. It is
required that the VDD starts at zero volts at power up or upon power cycling to ensure that there is no corruption
of the registers. If this is not possible, a reset must be initiated after power-up (i.e. when power is stable) with
the software reset command. Software reset command means setting bits 6, 4, and 3 in register Control_1 (00h)
logic 1 and all other bits logic 0 by sending the bit sequence 01011000 (58h), see Figure 8.

After sending the software reset command, it is recommended to re-initialize the interface by a STOP and START.

In reset state, all registers are set according to Table 7 and the address pointer returns to address 00h.
