NRDY Interrupt Enable Register (NRDYENB)
The NRDYENB register enables or disables the INTSTS0.NRDY flag to be set to 1 when the NRDY interrupt is
detected for each pipe.
On detecting the NRDY interrupt for the pipe corresponding to the bit in the NRDYENB register to which 1 has been set
by software, the USB sets 1 to the corresponding NRDYSTS.PIPEnNRDY flag (n = 0 to 9) and the INTSTS0.NRDY
flag. If INTENB0.NRDYE = 1 at this time, the USB generates the NRDY interrupt request.
While at least one PIPEnNRDY flag indicates 1, the USB generates the NRDY interrupt request when the corresponding
interrupt enable bit in the NRDYENB register is modified from 0 to 1 by software.
