Notes:
1. The measurement condition is VCC = 2.7 to 5.5 V and Topr = −40 to 85°C (J version) / −40 to 125°C (K version).
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.
