2. Automatic Stall by USB Function Module
(1) Transition from normal operation to stall
(2) When transaction is performed while 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 request or in the event of a USB specification
violation, the USB module automatically sets the internal status bit for the corresponding
endpoint without regarding to EPSTL0, and returns a stall handshake (1-1 in figure 12.14).
Once an internal status bit is set, it remains set until cleared by a Clear Feature request from
the host, without regarding to EPSTL0. After a corresponding bit is cleared by the Clear
Feature request, EPSTL0 is referred (3-1 in figure 12.14). The USB 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 12.14). To clear a
stall, therefore, the internal status bit must be cleared with a Clear Feature request (3-1 in
figure 12.14). If set by the firmware, EPSTL0 should also be cleared (2-1 in figure 12.14).
