IVAL Bit and EPB_RDY Bit
The IVAL bit is available per endpoint.
These IVAL bits can be specified by the CPU_EP bits and the DMA_EP bits, and the read/write is possible by
the IVAL bit of the CPU_FIFO Control Register and the IVAL bit of the Dn_FIFO Control Register.
The EPB_RDY bit can be set/cleared by the IVAL bit at each endpoint, irrespective of the aforesaid setting.
Similarly, the EPB_NRDY bit and EPB_EMP_OVR bit can be set/cleared regardless of the CPU_EP
bit/DMA_EP bit.
Make sure that the “1” setting to the EPB_RDY bit of the endpoint specified by the DMA_EP bit changes
according to the setting of the INTM bit.
