USB Upstream Port Status and Control
USB status and control is regulated by the USB Status and Control Register, as shown in
during reset.
USB Status and Control
Bits[2..0]: Control Action
Set to control action as per
the upstream port to be driven manually by firmware. For normal
USB operation, all of these bits must be cleared.
how the control bits affect the upstream port.
Table 13. Control Bit Definition for Upstream Port
Bit 3: Bus Activity
This is a “sticky” bit that indicates if any non idle USB event has
occurred on the upstream USB port. Firmware should check and
clear this bit periodically to detect any loss of bus activity. Writing
a ‘0’ to the Bus Activity bit clears it, while writing a ‘1’ preserves
the current value. In other words, the firmware clears the Bus
Activity bit, but only the SIE can set it.
Bits 4 and 5: D– Upstream and D+ Upstream
These bits give the state of each upstream port pin individually:
1 = HIGH, 0 = LOW.
