1.2.18.4.2 USB Control Register
The USB Control Register, shown in Figure 1.31, is used to control the USB FCU. This register is not reset by
a 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.
Figure 1.31: USB Control Register
1.2.18.4.3 USB Function Address Register
The USB Function Address Register, shown in Figure 1.32, 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 configured, the value is 0016. For the procedures on how to update this register, refer to Application
Notes USB Consecutive Set Address.
