State
AUTO_SET [7] R/W R If set, whenever the MCU writes MAXP data,
IN_PKT_RDY will automatically be set by the core
without any intervention from MCU.
If the MCU writes less than MAXP data, IN_PKT_RDY
bit has to be set by the MCU.
0
ISO [6] R/W R Used only for endpoints whose transfer type is
programmable.
1: Reserved
0: Configures endpoint to Bulk mode
0
MODE_IN [5] R/W R Used only for endpoints whose direction is
programmable.
1: Configures Endpoint Direction as IN
0: Configures Endpoint Direction as OUT
1
IN_DMA_INT_EN [4] R/W R Determine whether the interrupt should be issued or
not, when the IN_PKT_RDY condition happens. This is
only useful for DMA mode.
0 = Interrupt enable, 1 = Interrupt Disable
