Section 20 USB Function Module (USB)
20.10.7 Restrictions on Peripheral Module Clock (Pφ) Operating Frequency
Specify the peripheral module clock (Pφ) for the USB at 14 MHz or more. To set the USB
dedicated clock (cku) at 48 MHz, specify the peripheral module clock (Pφ) as shown in table 20.8.
Operation cannot be guaranteed if any frequency other than in the following table is specified.

20.10.8 Notes on Deep Software Standby Mode when USB is Used
1. Unlike software standby mode, deep standby software mode is canceled from the reset state.
2. If the RAMCUT bit is set to 1 when the USB enters deep software standby mode, the register
3. Set the USB module stop (MSTPC11) bit to 0 after canceling deep software standby mode.
4. If the DUSBIE bit is set to 0 when the USB enters deep software standby mode, software

states of the USB cannot be retained. When USB is used, set the RAMCUT bit to 1, and then,
make the USB enter deep software standby mode.
standby mode cannot be canceled through USB RESUME interrupt. Set the DUSBIE bit to 1,
and then, make the USB enter deep software standby mode.
