15.6.3 HcDirectAddressData register (R/W: 45H/C5H)
15.7.1 HcISTLBufferSize register (R/W: 30H/B0H)
15.7.2 HcISTL0BufferPort register (R/W: 40H/C0H)
15.7 Isochronous (ISO) transfer registers
Table 78:
This is a data port for the HCD to access the ISTL, INTL or ATL buffers under the
direct addressing mode.
Code (Hex): 45 — read
Code (Hex): C5 — write
Table 79:
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
Table 80:
In addition to the HcDirectAddressData register, the ISP1362 provides this register to
act as another data port for accessing the ISTL0 buffer. The starting address for
accessing the buffer is always fixed at 0000H. Therefore, random access of the ISTL0
buffer is not allowed. The bit description of the register is given in
