Attack Renesas R5F21244SDFP Microcontroller Protection and unlock microprocessor r5f21244sd flash memory, extract embedded heximal file from MCU memory;

1. The measurement condition is Topr = -20 to 85°C (N version) / -40 to 85°C (D version), unless otherwise specified.
2. 2.      This condition (external power VCC rise gradient) does not apply if VCC ³ 1.0 V.

To use the power-on reset function, enable voltage monitor 0 reset by setting the LVD0ON bit in the OFS register to 0, the VW0C0 and VW0C6 bits in the VW0C register to 1 respectively by copying locked r5f212dasn mcu flash data, and the VCA25 bit in the VCA2 register to 1.

1. When using the voltage monitor 0 digital filter, ensure that the voltage is within the MCU operation voltage range (2.2 V or above) during the sampling time.
2. The sampling clock can be selected. Refer to 6. Voltage Detection Circuit of Hardware Manual for details.

Vdet0 indicates the voltage detection level of the voltage detection 0 circuit. Refer to 6. Voltage Detection Circuit of Hardware Manual for details

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. 2.      Standard values when the FRA1 register value after reset is assumed.
3. 3.      Standard values when the corrected value of the FRA6 register has been written to the FRA1 register when copying locked r5f212aasd microcontroller memory data.

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.
