Unmask all interrupts with LDC instruction, etc.*
Finally, unmask the interrupts using the LDC instruction or the like and execute the SLEEP instruction immediately
afterward.

Procedure to enter power-down mode
Specify IRQ6 to falling edge sensitive
Set SPRSi and SPRSs in UIFR3 to 1
(Stop MSTPB0 in MSTPCRB to 1)
All USB module internal clocks stop
IRQ6 = Low (falling edge output)
(Write IRQ6SCB and IRQ6SCA
Detect USB bus suspend state
Enter USB module stop 2 state
Confirm SPRSs in UIFR3 as 1
(Execute SLEEP instruction)
Clear SPRSi in UIFR3 to 0
Enter power-down mode*
Clear IRQ6E in IER to 0 *
All LSI internal clocks stop

Procedure to cancel power-down mode
restarted by using various USB registers
USB communication operations can be
Wait for system clock stabilization time
(Wait for CK48READY in UIFR3 is set to 1)
(For crystal oscillator clock: 4 ms min.)
USB module intenal clock operation starts
(LSI internal clock starts oscillation)
(Clear MSTPB0 in MSTPCRB to 0)
(For external clok: 16 states min.)
Wait 2 ms for USB operation clock
IRQ6 = Low (falling edge output)
Cancel USB module stop2 mode
(USB operating clock stabilized)
Set CK48READY in UIFR3 to 1
Clear SPRSs of UIFR3 to 0
Clear SPRSi in UIFR3 to 0
Cancel power-down mode
Set SPRSi of UIFR3 to 1
Detect USB bus resume
Set SOF of UIFR3 to 1
Set IRQ6F in ISR to 1
Detect SOF packet
USPND pin = Low
Enter active mode
IRQ6 = High
