Pins, the CPU and SFR are reset by using the built-in voltage detection circuit, which monitors the voltage
applied to the V
When the VC26 bit in the VCR2 register is set to "1" (reset level detection circuit enabled), pins, the CPU
and SFR are reset as soon as the voltage applied to the V
Then, pins, the CPU and SFR are reset as soon as the voltage applied to the V
above. The microcomputer executes the program in an address determined by the reset vector.
The microcomputer executes the program after detecting Vdet3r and waiting
registers are reset by the hardware reset 1 and brown-out detection reset, and are also placed in the same
reset state.
The microcomputer cannot exit stop mode by brown-out detection reset.
Figure 5.3 shows an example of brown-out detection reset operation.
