Register 2.
The voltage detecting circuit is controlled by the Voltage Detect Control Register 1 and Voltage Detect Control
Note 1: The VDCR1 is initialized by a power-on reset or an external reset input. *; Don't care
Note 2: If the VD2F or VD1F bit is cleared by software at the same time as it is set by detection of a low-voltage condition, the set-
Note 3: Be sure to write “0” to VDCR1 Register bits 7 and 5, and write "1" to VDCR1 Register bit 4.
Note 4: The values of the VDCR1 Register bit 6 is indeterminate when read.
Note 1: Note: The VDCR2 is only initialized by a power-on reset or an external reset input. *; Don't care
Note 2: Be sure to write “0” to VDCR2 Register bits 3 and 2.
