Section 23 USB 2.0 Host/Function Module (USB)
(12) SIGN Interrupt
The SIGN interrupt is generated when an ACK response for the transmitted setup packet has not
been received from the peripheral side with the host controller function selected. The SIGN
interrupt can be used to detect no ACK response transmitted from the peripheral side or corruption
of an ACK packet.
23.4.3 Pipe Control
Table 23.14 lists the pipe setting items of this module. With USB data transfer, data transmission
has to be carried out using the logic pipe called the endpoint. This module has eight pipes that are
used for data transfer.
Settings should be entered for each of the pipes in conjunction with the specifications of the
system.
