66AK2H06: USB interrupts

Koichiro Tashiro

Part Number: 66AK2H06

Hi,

I have a question from my customer for USB interrupts in 66AK2H06.

According to USB3.0 users guide(spruhj7a.pdf) section 2.11.1, there are total 18 interrupts.
But datasheet(sprs866g) table 8-23 shows only 7 interrupts for ARM.
USB_INT05 to USB_INT15 are missing. These missing interrupts cannot be used?

Thanks and regards,
Koichiro Tashiro

Hi, Koichiro,

Sorry for the delay. As the datasheet shown, ARM only has the secondary event ring interrupts USB_INT01-04. USB_INT05-11 event ring interrupts belong to DSP which ARM can't use. USB_INT12-15 are not connected and can't be used either.
