Universal Serial Bus Peripheral Ready (PRUSB)
The PRUSB register indicates whether the USB module is ready to be accessed by software following a change in status of power, run mode clocking, or reset. A power change is initiated if the corresponding PCUSB bit is changed from 0 to 1. A run mode clocking change is initiated if the corresponding RCGCUSB bit is changed. A reset change is initiated if the corresponding SRUSB bit is changed from 0 to 1.
The PRUSB bit is cleared on any of the preceding events and is not set again until the module is completely powered, enabled, and internally reset.
PRUSB is shown in Figure 4-184 and described in Table 4-212.
