User manual
9.6.5 Register interface
9.6.6 SoftConnect
The Register Interface allows the CPU to control the operation of the USB Device
Controller. It also provides a way to write transmit data to the controller and read receive
data from the controller.
The connection to the USB is accomplished by bringing USB_DP (for a full-speed device)
HIGH through a 1.5 kOhm pull-up resistor. The SoftConnect feature can be used to allow
software to finish its initialization sequence before deciding to establish connection to the
USB. Re-initialization of the USB bus connection can also be performed without having to
unplug the cable.
To use the SoftConnect feature, the USB_CONNECT signal should control an external
switch that connects the 1.5 kOhm resistor between USB_DP and 3.3 V. Software can
then control the USB_CONNECT signal by writing to the CON bit using the SIE Set
Device Status command.
Transactions on the USB bus transfer data between device endpoints and the host. The
direction of a transaction is defined with respect to the host. OUT transactions transfer
data from the host to the device. IN transactions transfer data from the device to the host.
All transactions are initiated by the host controller.
