This is a data port for the HCD to access the ISTL, INTL or ATL buffers under direct
addressing mode.
Code (Hex): 45 — read
Code (Hex): C5 — write
This register requires you to allocate the size of the buffer to be used for ISO transactions.
The buffer size specified in the register is applied to the ISTL0 and ISTL1 buffers.
Therefore, ISTL0 and ISTL1 always have the same buffer size.

Code (Hex): 30 — read
Code (Hex): B0 — write
In addition to the HcDirectAddressData register, the ISP1362 provides this register to act
as another data port to access the ISTL0 buffer. The starting address to access the buffer
is always fixed at 0000h. Therefore, random access of the ISTL0 buffer is not allowed. The
