## NOTES:
based on datasheet (BK8000L_datasheet.pdf) BK8000L has support for SDcard:
| PIN |function|
|-----------|------------|
| GPIO12 |sd_clk/clk13m|
| GPIO13 |sd_cmd/SCL|
| GPIO14 |sd_data[0]/SDA|
| GPIO15 |sd_data[1]|
| GPIO16 |sd_data[2]|
| GPIO17 |sd_data[3]|
wakeup:
The BK8000L can enter into shut down mode when there is no active connection. The shut mode can be waked up by GPIO and USB charge.
All GPIO can be source to wake up MCU from shut down state. In shut down state, any level change on the set GPIO will trigger the wake up procedure.
