C (standard mode).
*1: Only channel 5, channel 6 and channel 11 support the I
*2: The initial detection voltage of the external low voltage detection is 2.8 V ± 8 % (2.576 V to 3.024 V). This LVD setting
and internal LVD cannot be used to reliably generate a reset before voltage dips below minimum guaranteed operation
voltage, as these detection levels are below the minimum guaranteed MCU operation voltage. Below the minimum
guaranteed MCU operation voltage, MCU operations are not guaranteed with the exception of LVD.
I did it on the 4412 of cortex A9, and used the gpio port to simulate its communication. A 10K pull-up resistor was connected to the data line sda, but I couldn't read the data and couldn't receive th...
I really want to learn how to program, but I don't know where to start. I hope everyone can give me some advice to help me make progress together. Thank you....
