Notes:
1. Vcc = 1.8 V to 5.5 V, Topr = -20 °C to 85 °C (N version)/-40 °C to 85 °C (D version), unless otherwise specified.
2. 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.
Note:
1. Vcc = 1.8 V to 5.5 V, Topr = -20 °C to 85 °C (N version)/-40 °C to 85 °C (D version), unless otherwise specified.
Notes:
1. The measurement condition is Vcc = 1.8 V to 5.5 V and Topr = 25 °C.
2. Wait time until the internal power supply generation circuit stabilizes during power-on.
