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.

Table 65. Device n Endpoint n Count Register
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.
