18.6.3
When a stall setting is made with the Set Feature command, or in the event of a USB specification
violation, the USB function module automatically sets the internal status bit for the relevant
endpoint without regard to the EPSTL register, and returns a stall handshake (1-1 in figure 18.14).
Once an internal status bit is set, it remains set until cleared by a Clear Feature command from the
host, without regard to the EPSTL register. After a bit is cleared by the Clear Feature command,
EPSTL is referenced (3-1 in figure 18.14). 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 18.14). To clear a stall, therefore,
the internal status bit must be cleared with a Clear Feature command (3-1 in figure 18.14). If set
by the application, EPSTL should also be cleared (2-1 in figure 18.14).
