12.8.1
The following must be noted for the EP0s FIFO used to receive 8-byte setup data.
The USB is designed to always receive setup requests. Accordingly, write from the USB bus has
higher priority than read from CPU. If the reception of the next setup request starts while CPU is
reading data after completing reception, this data read from CPU is forcibly cancelled and the next
setup request write starts. After the next setup request write, data read from CPU is thus
undefined.
12.8.2
If the USB cable is disconnected during communication, old data may be contained in the FIFO.
Accordingly, FIFOs must be cleared immediately after USB cable connection.
Note, however, that FIFOs that are currently used for data transfer to or from the host must not be
cleared.
12.8.3
The system clock (φ) must range from 31 MHz to 33 MHz.
12.8.4
This module uses signals in which each bit in IFR0 is logical-ORed as interrupt requests. Thus,
even if a flag is cleared, the request is not negated while at least one of other flags is set.
12.8.5
In this module, all registers should be accessed in 32-bit units using the MOV.L instruction. They
cannot be accessed in 8- or 16-bit units using instructions such as MOV.W, MOV.B, or bit
manipulation instruction.
