Notes:
1. VCC = 1.8 to 5.5 V, Topr = 20 to 85 C (N version) / 40 to 85 C (D version), unless otherwise specified.
2. This indicates the precision error for the oscillation frequency of the high-speed on-chip oscillator.
3. 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 to 5.5 V, Topr = 20 to 85 C (N version) / 40 to 85 C (D version), unless otherwise specified.
Notes:
1. The measurement condition is VCC = 1.8 to 5.5 V and Topr = 25 C.
2. Waiting time until the internal power supply generation circuit stabilizes during power-on.
