Note 1
You must write
"1"
to
bit4.
2. When the power supply voltage rises, the reset state must be
maintained through the voltage detection circuit
or external reset
before the power supply voltage reaches the working voltage range shown in the
AC
characteristics of the data sheet
; When the supply voltage drops, it must be reset by transferring in deep sleep
mode,
voltage detection circuitry, or external reset before the supply voltage falls below the operating voltage range.
The operating voltage range depends on the setting of the user option byte (000C2H).
