Part Number: TMS320F28377S

Hi,

My customer uses USB in device mode. This mode generates a USB interrupt (SOF) at 1ms intervals.

Is it possible to disable this interrupt for a period of time?

They want this interrupt disabled for a period of time. (e.g. GPIO interrupts are not delayed)

Hi Sasaki-san,

Yes, they can use Interrupt_disable(INT_USBA) driverLib function. Another option is to not clear the PIE Interrupt Group within the ISR in certain conditions, line of code for this is below.

Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP9);

Best,

Kevin
