Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 31-8 Unimplemented: Read as ‘0’

bit 7 LSPD: Low-Speed Direct Connection Enable bit (Host mode and U1EP0 only)

1 = Direct connection to a Low-Speed device enabled

0 = Direct connection to a Low-Speed device disabled; hub required with PRE_PID

bit 6 RETRYDIS: Retry Disable bit (Host mode and U1EP0 only)

1 = Retry NAKed transactions disabled

0 = Retry NAKed transactions enabled; retry done in hardware

bit 5 Unimplemented: Read as ‘0’

bit 4 EPCONDIS: Bidirectional Endpoint Control bit

If EPTXEN = 1 and EPRXEN = 1:

1 = Disable Endpoint n from Control transfers; only TX and RX transfers allowed

0 = Enable Endpoint n for Control (SETUP) transfers; TX and RX transfers also allowed

Otherwise, this bit is ignored.

bit 3 EPRXEN: Endpoint Receive Enable bit

1 = Endpoint n receive is enabled

0 = Endpoint n receive is disabled

bit 2 EPTXEN: Endpoint Transmit Enable bit

1 = Endpoint n transmit is enabled

0 = Endpoint n transmit is disabled

bit 1 EPSTALL: Endpoint Stall Status bit

1 = Endpoint n was stalled

0 = Endpoint n was not stalled

bit 0 EPHSHK: Endpoint Handshake Enable bit

1 = Endpoint Handshake is enabled

0 = Endpoint Handshake is disabled (typically used for isochronous endpoints)
