Address Setup
AT90USB82/162
Figure 20-2. Endpoint activation flow:
As long as the endpoint is not correctly configured (CFGOK cleared), the hardware does not
acknowledge the packets sent by the host.
CFGOK will not be set if the Endpoint size parameter is bigger than the DPRAM size.
A clear of EPEN acts as an endpoint reset (see Section 20.3, page 196 for more details). It also
performs the next operation:
See Section 19.6, page 190 for more details about the memory allocation/reorganization.
The USB device address is set up according to the USB protocol:
ADDEN and UADD shall not be written at the same time.
UADD contains the default address 00h after a power-up or an USB reset.
• The configuration of the endpoint is kept (EPSIZE, EPBK, ALLOC kept)
• It resets the data toggle field.
• The DPRAM memory associated to the endpoint is still reserved.
• the USB device, after power-up, responds at address 0
• the host sends a SETUP command (SET_ADDRESS(addr)),
• the firmware records that address in UADD, but keep ADDEN cleared,
• the USB device sends an IN command of 0 bytes (IN 0 Zero Length Packet) to acknowledge
• then, the firmware may enable the USB device address by setting ADDEN. The only
the transaction,
accepted address by the controller is the one stored in UADD.
