RX23W Group 32. USB 2.0 Host/Function Module (USBc)
32.2.9 BRDY Interrupt Enable Register (BRDYENB)
The BRDYENB register enables or disables the INTSTS0.BRDY flag to be set to 1 when the BRDY interrupt is detected
for each pipe.
On detecting the BRDY interrupt for the pipe corresponding to the bit in the BRDYENB register to which 1 has been set
by software, the USB sets 1 to the corresponding BRDYSTS.PIPEnBRDY flag (n = 0 to 9) and the INTSTS0.BRDY
flag. If INTENB0.BRDYE = 1 at this time, the USB generates the BRDY interrupt request.
While at least one PIPEnBRDY flag indicates 1, the USB generates the BRDY interrupt request when the corresponding
interrupt enable bit in the BRDYENB register is modified from 0 to 1 by software.
