PCA9698 sample code

[lanjinxiang]

Hello, All:

Could you please send me a sample code to output a high level from Bank0 I/O0?

My PCA9698 salve address is 0x40(8bit).

I already write PCA9698 successfully,I2C respond is ACK.

for example,

0x20,0x08,0x01;  //set Bank0 as output:

But which register is used for sending command to pull high or pull down I/O?

Could you please send me a sample code?
