Table 12.4 FIFO Size in Each Transfer Mode
12.8.9
The USVBUS pin of this LSI must be connected to the USB connector's VBUS pin via a level
shifter. (Make sure the polarity is correct.) This is because the USB module has a circuit that
operates by detecting USB cable connection or disconnection.
Even if the power of the device incorporating this module is turned off, 5-V power is applied to
the USB connector's VBUS pin while the USB cable is connected to the device set. To protect the
LSI from destruction, use an external level shifter which allows voltage application to the pin even
when the power is off.
12.8.10 USB 2.0 Transceiver (Physical Layer)
This module does not include the USB 2.0 transceiver. Therefore an external transceiver should be
used.
12.8.11 EPDR0s Read
EPDR0s must be read in 8-byte units. Otherwise, the data received in the next setup cannot be
read normally.
12.8.12 USB Bus Idle in High-Speed Mode
When the USB bus enters the idle state in high-speed mode, this module enters full-speed mode.
However, the MODE MN1 and MODE MN0 bits in IFR0 are not changed. Therefore, the
MODEF bit in IFR0 is not set.
