5.12 DSPORT logic
DSPORT (downstream port) logic implements the control logic defined in section 11.5 of USB
specification Revision 2.0. It mainly manipulates the state machine, the connection/disconnection detection,
over current detection and power enable control, and the status LED control of the downstream port.
Besides, it also output the control signals to the DSPORT transceiver.
5.13 DSPORT Transceiver
DSPORT transceiver is the analog circuit that supports high-speed, full-speed, and low-speed electrical
characteristics defined in chapter 7 of USB specification Revision 2.0. In addition, each DSPORT
transceiver accurately controls its own squelch level to detect the detachment and attachment of devices.
5.2 Configuration and I/O Settings
5.2.1 RESET# Setting
GL852 integrates in the pull-up 1.5K
resister of the upstream port. When RESET# is enabled, the internal
1.5K
pull-up resister will be disconnected to the 3.3V power. To meet the requirement (p.141) of the USB
2.0 specification, pull-up resister should be disconnected while lacking of USB cable power (Vbus).
Therefore, we suggest designing the RESET# circuit as following figure to meet the requirement mentioned
above.
