USB Control Register
USB Function Address Register
The USB Control Register, shown in Figure 1.45, is used to control the USB FCU. This register is not reset by USB reset
signaling. After the USB is enabled (USBC7 set to "1"), a minimum delay of 250ns (three 12 MHz clock periods) is
needed before performing any other USB register read/write operations.
• USBC5 (USB Clock Enable):
The USB clock enable bit is used to enable or disable the USB clock (fUSB). This clock is derived from the Frequency
Synthesizer and is required for USB operation.
• USBC6 (SOF port select):
The SOF port select bit enables or disables outputting a SOF signal on the P9
active low pulse is output each time a start of frame packet is detected on the USB. The output pulse width is 166ns (two
12MHz USB clock cycles).
• USBC7 (USB Enable):
The USB enable bit is used to enable or disable the USB block. Make sure the USB clock is enabled before setting this
bit to "1".
The USB Function Address Register, shown in Figure 1.46, maintains the 7-bit USB address assigned by the host. The
USB FCU uses this register value to decode USB token packet addresses. At reset, when the device is not yet config-
ured, the value is 00
