Write:
This bit is set to enable endpoint 2 to respond to addressed IN packet
tokens. Reset clears this bit.
This bit is set to enable endpoint 1 to respond to addressed IN packet
tokens. Reset clears this bit.
This bit is set to generate the STALL handshake packet as next IN
transaction handshake packet from endpoint 2. Reset clears this bit.
This bit is set to generate the STALL handshake packet as next IN
transaction handshake packet from endpoint 1. Reset clears this bit.
1 = Endpoint 2 enabled; and responds to IN tokens
0 = Endpoint 2 disabled
1 = Endpoint 1 enabled; and responds to IN tokens
0 = Endpoint 1 disabled
1 = Send STALL handshake on endpoint 2
0 = Do not send STALL handshake on endpoint 2
1 = Send STALL handshake on endpoint 1
0 = Do not send STALL handshake on endpoint 1
