(3) Automatic Stall by USB Function Module
(1) Transition from normal operation to stall
(2) When transaction is performed whill internal status bit is set
(3) When Clear Feature is sent before transaction is performed
When a stall setting is made with the Set Feature command, when the information of this
module differs from that returned to the host by the Get Descriptor, or in the event of a USB
specification violation, the USB function module automatically sets the internal status bit for
the corresponding endpoint without regarding to EPnSTL, and returns a stall handshake (1-1 in
figure 14.21).
Once an internal status bit is set, it remains set until cleared by a Clear Feature command from
the host, without regarding to EPnSTL. After a bit is cleared by the Clear Feature command,
EPnSTL is referred (3-1 in figure 14.21). The USB function module continues to return a stall
handshake while the internal status bit is set, since the internal status bit is set even if a
transaction is executed for the corresponding endpoint (2-1 and 2-2 in figure 14.21). To clear a
stall, therefore, the internal status bit must be cleared with a Clear Feature command (3-1 in
figure 14.21). If set by the firmware, EPnSTL should also be cleared (2-1 in figure 14.21).
