cycle error (INTUSBH1). Accessing misaligned addresses is prohibited since the address is regarded as being
discontinuous. Only accessing 32-bit-aligned continuous addresses is considered to be an access to a continuous
address, and operates normally (see Figure 21-3).
The V850ES/JG3-U and V850ES/JH3-U are connected to the USB host controller via the PCI bus bridge via a 16-

2nd Cycle
[Continous]
The address is continous and is a
32-bit address, so it is
"continous". Whether 00H or
02H comes first does not matter.
[Discontinous]
Even if the address is continuous,
if it is not 32-bit aligned, it is not
considered to be continous.
