Data Sheet
Table 18
The EPEC Transmit Byte Length registers (x) provide the 10-bit Transmit bytes length of
the actual packet to be send to the USB endpoint#x and the related bit. Each EPEC
channel can be cleared by SW, if necessary.
All USB source and destination pointers will be used in either receive or transmit
direction, since the USB endpoint’s direction of data is SW-configurable as IN, OUT or
bidirectional (except endpoint 0) after USB device controller reset.
EPEC_INT_REG
Table 19
The EPEC interrupt register indicates the end of an TX-packet transfer for an USB
endpoint.
