Figure 6.5
To use voltage monitor 0 reset, set the LVDAS bit in the OFS register to 0 (voltage monitor 0 reset enabled after
reset).
Figure 6.5 shows an Operating Example of Voltage Monitor 0 Reset.
Voltage Monitor 0 Reset
Internal reset signal
When the internal reset signal is driven low, the pins, CPU, and SFRs are initialized.
When the internal reset signal level changes from low to high,
a program is executed beginning with the address indicated by the reset vector.
Refer to 4. Special Function Registers (SFRs) for the states of the SFRs after reset.
