Crack Renesas Microcontroller R5F21236KFP Flash Program and extract MCU embedded firmware from R5F21236 which will restore the functionality of Microprocessor R5F21236;
NOTES:
The measurement condition is VCC = 2.7 V to 5.5 V and Topr = -40°C to 85°C (J version) / -40°C to 125°C (K version).
2. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2 register to 0.
3. Hold Vdet2 > Vdet1.
4. This parameter shows the voltage detection level when the power supply drops. The voltage detection level when the power supply rises is higher than the voltage detection level when the power supply drops by approximately 0.1 V.
5. Time until the voltage monitor 1 reset is generated after the voltage passes Vdet1 when VCC falls. When using the digital filter, its sampling time is added to td(Vdet1-A). When using the voltage monitor 1 reset, maintain this time until VCC = 2.0 V after the voltage passes Vdet1 when the power supply falls which can be taken advantage of unlocking renesas r5f212ba flash memory.
