Hello,

I'd like to interpret the value epStatus (type of CyU3PUsbHostEpStatus_t ) which shows the transfer status.

However, so far I couldn't find any material which deals with it even on the FX3API guide and examples etc.

It would be great if someone can lead me to the relevant information.

Here are some of my logs on epStatus for example.

CyFxHostXferCb ep=0x81,epStatus=0x578081

CyFxHostXferCb ep=0x81,epStatus=0x1C78081

CyFxHostXferCb ep=0x81,epStatus=0x1

CyFxHostXferCb ep=0x81,epStatus=0x378081

CyFxHostXferCb ep=0x81,epStatus=0x1

CyFxHostXferCb ep=0x81,epStatus=0x578081

CyFxHostXferCb ep=0x81,epStatus=0x378081

Thanks for any comments.

Hello,

When the callback function is invoked, the value inside epStatus will be in accordance to the Table 6-5 of FX3 TRM. The snapshot of the same is given below:

Please note that there is a small mistake in the description of bit 6 (Halt) of this table. It should be as follows:

0: EP is not halted

1: EP is halted
