VNF9Q20F OUT CONTROL USING DIO PINS

[Darshanvenkataramu]

Hi Everyone, 

 

I'm working on VNF9Q20F and VNF9D5F , I have an issue where I can’t control OUT (ON/OFF) BY SPI or by DIO . 

 

Once the VNF is in normal mode.

• Below are the commands which are I ‘m sending: 
• 0x0h: 0x0 0x00 0x3F 0xF1,
• 0x03h: 0x0 0x03 0x3F 0xF1,
• 0x13:  0x0 0x13 0x0F 0x00,
• 0x0B: 0x0 0x0B 0x1F 0xF4,
• 0x08h: 0x0 0x08 0x1F 0xF4,
• DIO: 0, DIO 1. 

 

1. Even after sending the above commands, out control is not possible.
