Tool/software:
1. When entering Test Mode 4, which register is being operated when writing, 0x0904 or 0x0453?
2. When reading the current Test Mode, is it the 0x2904 register?
3. When setting the master-slave mode, is it the 0x0834 register, and the device address is 0x1?
4. When reading the current mode, is it the 0x2834 register, and the device address is 0x1?
5. What is the waveform of each test mode (1,2,4,5,6,7) under the oscilloscope? Are there any pictures?
