0Selecting the supply voltage monitoring threshold setting of 2.1 volts.
1Selecting the supply voltage monitoring threshold setting of 1.6 volts.
Supply Voltage Monitoring Threshold Selection Bit
The VDSL bit is intended to select the supply voltage monitoring threshold settings.
Indicating supply voltage above the supply voltage monitoring threshold settings.
Indicating supply voltage below the supply voltage monitoring threshold settings.
Supply Voltage Monitoring Result Indication Bit
Once the VDET bit is set to 1, the supply voltage monitoring circuit will be disabled while the VDET bit will hold the
setting of 1. The VDET bit accepts only the writing of 0, which restarts the supply voltage monitoring circuit.
Conversely, setting the VDET bit to 1 causes no event.
2.2 Control Register 2 (at Address Fh)
(For write operation)
(For read operation)
The SCRATCH bit is intended for scratching and accepts the reading and writing of 0 and 1. The SCRATCH bit will
be set to 0 when the XSTP bit is set to 1 in the control register 2.
*) Default settings: Default value means read/written values when the XSTP bit is set to “1” due to power-on from 0 volts or supply voltage drop.
