EP2_RX_FUNC_ADDR_REG 0x0094
7
RW
0
Records the address of the target function that is
to be accessed through endpoint2 for receive.
Required in Host mode.
EP2_RX_HUB_ADDR_REG
0x0096
8
RW
0
Needs to be written where a full speed or low
speed device is connected to receive endpoint2
through a high speed USB 2.0 hub which carries
out the necessary transaction translation to
convert between high speed transmission and
full speed/low speed transmission. In such
circumstances:
– The lower 7 bits should record the address of
this USB 2.0 hub.
– The top bit records whether the hub has
multiple transaction translators (set to ‘0’ if single
transaction translator; set to ‘1’ if multiple
transaction translators). This is relevant in Host
mode only.
EP2_RX_HUB_PORT_REG
0x0097
7
RW
0
Needs to be written where a full speed or low
speed device is connected to receive endpoint2
via a high speed USB 2.0 hub which carries out
the necessary transaction translation. In such
circumstances, these 7-bit read/write registers
need to be used to record the port of that USB
2.0 hub through which the target associated with
the endpoint0 is accessed. This is only relevant
in Host mode.
EP3_TX_FUNC_ADDR_REG 0x0098
7
RW
0
Records the address of the target function that is
to be accessed through endpoint3 for transmit.
Required in Host mode.
EP3_TX_HUB_ADDR_REG
0x009A
8
RW
0
Needs to be written where a full speed or low
speed device is connected to transmit endpoint3
through a high speed USB 2.0 hub which carries
out the necessary transaction translation to
convert between high speed transmission and
full speed/low speed transmission. In such
circumstances:
– The lower 7 bits records the address of this
USB 2.0 hub.
– The top bit records whether the hub has
multiple transaction translators (set to ‘0’ if single
transaction translator; set to ‘1’ if multiple
transaction translators). This is relevant in Host
mode only.
