Note:
1. To use the power-on reset function, enable voltage monitor 0 reset by setting the LVDAS bit in the OFS register to 0.
Figure 4.3 Power-on Reset Circuit Characteristics
Notes:
1. This enables the setting errors of bit rates such as 9600 bps and 38400 bps to be 0% when the serial interface is used in
UART mode.
2. This indicates the precision error for the oscillation frequency of the high-speed on-chip oscillator.
