VBAT and VINT are the two power domains on the device.

When the following condition is met, a power-on reset (POR) occurs:

• VBAT domain – VBAT > VBAT_{POR_RISING}
• VINT domain – VINT > VINT_POR

When the following condition is met, a brownout reset (BOR) occurs in the VINT domain and the device enters the COLD START state:

• VINT < VINT_BOR

When the following condition is met, a reset occurs in the VBAT domain and the device enters the NO SUPPLY state:

• VBAT < VBAT_{POR_FALLING}
