Register Description
The Device n Endpoint n Address Register is used as the base pointer into memory space for the current Endpoint transaction.
There are a total of eight endpoints for each of the two ports. All endpoints have the same definition for their Device n Endpoint
n Address Register.
Address (Bits [15:0])
The Address field sets the base address for the current transaction on a signal endpoint.
Device n Endpoint n Count Register [R/W]
Register Description
The Device n Endpoint n Count Register designates the maximum packet size that can be received from the host for OUT
transfers for a single endpoint. This register also designates the packet size to be sent to the host in response to the next IN token
for a single endpoint. The maximum packet length is 1023 bytes in ISO mode. There are a total of eight endpoints for each of the
two ports. All endpoints have the same definition for their Device n Endpoint n Count Register.
Count (Bits [9:0])
The Count field sets the current transaction packet length for a single endpoint.
Reserved
All reserved bits should be written as ‘0’.
