NOTES:
1. VCC = 2.2 to 5.5 V, Topr = -20 to 85
°C (N version) / -40 to 85°C (D version), unless otherwise specified.
2. These standard values show when the FRA1 register value after reset is assumed.
3. These standard values show when the corrected value of the FRA6 register is written to the FRA1 register.
4. 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 = 2.2 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 = 2.2 to 5.5 V and Topr = 25
°C.
2. Waiting time until the internal power supply generation circuit stabilizes during power-on.
3. Time until system clock supply starts after the interrupt is acknowledged to exit stop mode.
