1.2.18.4.6 USB Interrupt Enable Registers 1 and 2
The USB Interrupt Enable Registers 1 and 2, shown in Figure 1.36 and Figure 1.37, are used to enable the
corresponding interrupt status conditions that can generate a USB Function Interrupt. When the bit to a cor-
responding interrupt condition is “0”, that condition does not generate a USB function interrupt. When the bit
is a “1”, that condition can generate a USB function interrupt. At reset, all USB function interrupt status condi-
tions are enabled.
