bit 19-16 TXFIFOSZ<3:0>: TX Endpoint FIFO packet size bits

The maximum packet size to allowed for (before any splitting within the FIFO of Bulk/High-Bandwidth

packets prior to transmission)

1111 = Reserved

•

1010 = Reserved

1001 = 4096 bytes

1000 = 2048 bytes

0111 = 1024 bytes

0110 = 512 bytes

0101 = 256 bytes

0100 = 128 bytes

0011 = 64 bytes

0010 = 32 bytes

0001 = 16 bytes

0000 = 8 bytes

bit 15-10 Unimplemented: Read as ‘0’

bit 9 TXEDMA: TX Endpoint DMA Assertion Control bit

1 = DMA_REQ signal for all IN endpoints will be deasserted when MAXP-8 bytes have been written to an

endpoint. This is Early mode.

0 = DMA_REQ signal for all IN endpoints will be deasserted when MAXP bytes have been written to an

endpoint. This is Late mode.

bit 8 RXEDMA: RX Endpoint DMA Assertion Control bit

1 = DMA_REQ signal for all OUT endpoints will be deasserted when MAXP-8 bytes have been written to

an endpoint. This is Early mode.

0 = DMA_REQ signal for all OUT endpoints will be deasserted when MAXP bytes have been written to an

endpoint. This is Late mode.

bit 7 BDEV: USB Device Type bit

1 = USB is operating as a ‘B’ device

0 = USB is operating as an ‘A’ device

bit 6 FSDEV: Full-Speed/Hi-Speed device detection bit (Host mode)

1 = A Full-Speed or Hi-Speed device has been detected being connected to the port

0 = No Full-Speed or Hi-Speed device detected

bit 5 LSDEV: Low-Speed Device Detection bit (Host mode)

1 = A Low-Speed device has been detected being connected to the port

0 = No Low-Speed device detected

bit 4-3 VBUS<1:0>: V

BUS Level Detection bits

11 = Above V

BUS Valid

10 = Above AValid, below V

BUS Valid

01 = Above Session End, below AValid

00 = Below Session End

bit 2 HOSTMODE: Host Mode bit

1 = USB module is acting as a Host

0 = USB module is not acting as a Host

bit 1 HOSTREQ: Host Request Control bit

‘B’ device only:

1 = USB module initiates the Host Negotiation when Suspend mode is entered. This bit is cleared when

Host Negotiation is completed.

0 = Host Negotiation is not taking place
