6 Pin
In the Initial Status, the I/O Ctrl and the Target Power can be
selected to perform the corresponding operations.
6 Pin
8 Pin
1. In 8 Pin Mode, the I/O Ctrl and the Target Power are
selected, but they are forbidden to perform any operation.
2. When the Mode is switched into the 6 Pin Mode, the I/O
Ctrl and the Target Power can be selected to perform the
corresponding operations.
8 Pin
I2C Trigger
1. When the Mode is switched into the 8 Pin Mode
automatically, the I/O Ctrl and the Target Power are selected,
but they are forbidden to perform any operation.
2. When the Mode is exited in the I2C Trigger Mode, the Mode
will keep in the 8 Pin Mode.
8 Pin
SPI Trigger
1. When the Mode is switched into the 8 Pin Mode
automatically, the I/O Ctrl and the Target Power are selected,
but they are forbidden to perform any operation.
2. When the Mode is exited in the SPI Trigger Mode, the
Mode will keep in the 8 Pin Mode.
8 Pin
I2C Batch
1. When the Mode is switched into the 8 Pin Mode
automatically, the I/O Ctrl and the Target Power are selected,
but they are forbidden to perform any operation.
2. At this moment, the 6 Pin Mode can not be selected in the
GPIO of I2C Mode.
3. When the Mode is exited in the I2C Batch Mode, the Mode
