As not shown in figure 12.2, when the MODE F bit in IER0 is set to 1 and the MODE MN0 and
MODE MN1 bits in IFR0 are changed, an interrupt occurs. This interrupt can be used to manage
the bulk maximum packet size and descriptor information.
12.5.2
If the USB cable enters the disconnection state from the connection state, perform the operation as
shown in figure 12.3.
As not shown in figure 12.3, when the MODE F bit in IER0 is set to 1 and the MODE MN0 and
MODE MN1 bits in IFR0 are changed, an interrupt occurs.

USB Cable Disconnection
Wait for USB cable connection
During USB cable connection
MODE MN 0/1 in IFR0 = 01
MODE MN 0/1 in IFR0 = 10
MODE MN 0/1 in IFR0 = 00
MODE MN 0/1 in IFR0 = 00
USB cable disconnection
VBUS MN in IFR0 = 0
In high-speed mode:
VBUS F in IFR0 = 1
In full-speed mode:
USVBUS pin = low
