Note 1. When OFS1.(STUPLVD1REN, FASTSTUP) = 11b.
Note 2. When OFS1.(STUPLVD1REN, FASTSTUP) = 10b.
Note 3. When OFS1.STUPLVD1REN = 0.
Note 4. Turn on the power supply voltage according to the normal startup rising gradient because the register settings set by OFS1 are
not read in boot mode.

The ripple voltage must meet the allowable ripple frequency f_r(VCC) within the range between the VCC upper limit (3.6 V) and
lower limit (1.8 V).
When VCC change exceeds VCC ±10%, the allowable voltage change rising/falling gradient dt/dVCC must be met.
