placed in the ATL RAM at the same time. A paired PTD is designed specially for
high performance of a single endpoint. They are identi
fi
ed by hardware by using
the
‘
Paired
’
bit in the PTD.
Possible to send up to a maximum of 18 USB bulk packets in 1 ms frame
(1.152 Mbyte/s) by using the paired PTD feature.
Provides the status of every transfer endpoints (PTD) by monitoring the
HcATLDoneMap of the ISP1362. This register provides information on which PTD
transfers are complete.
Sets the IRQ after the user-speci
fi
ed number of transfers is done.
Skips any PTD that is wasting bandwidth by using HcATLSkipMap.
12.5.1
Sending a USB device request (Get Descriptor)
This section provides an example on how a USB transfer descriptor
‘
Get Descriptor
’
(commonly used in device enumeration) is used to illustrate the ISP1362 PTD
application. To perform this example, make sure the ISP1362 is in the Operational
state, and then connect a USB device (for example, a USB mouse) to a port.
Remark:
For details on the USB device request, refer to Chapter 9 of
Universal Serial
Bus Speci
fi
cation Rev. 2.0
.
Step 1:
Set the HcATLBlockSize, HcATLSkip and HcATLLast registers to 0x0008,
0xFFFE and 0x0001, respectively.
Step 2:
A PTD is then constructed based on the information given in the following
sample code. This sample code places information into the correct bit location within
the 8 bytes of the PTD structure.
ActualBytes (10 bits) = 0x00
CompletionCode (4 bits) = 0x0F
Active (1 bit) = 1
Toggle (1 bit) = 0
MaxPacketSize (10 bits) = 8
EndpointNumber (4 bits) = 0
Speed (1 bit) = 0 (full-speed; use 1 for low-speed)
DirToken (2 bits) = 0 (setup token)
TotalBytes (10 bits) = 8
CompletedPTD
0xF800, 0x0008, 0x0008, 0x0000
Step 3:
This array is then appended with an 8-byte payload that speci
fi
es the type of
request the HC wants to send. For example, for Get Descriptor, the payload is
0x0680, 0x0100, 0x0000, 0x0012.
Step 4:
The 16 bytes of data is now a complete PTD with an accompanying payload.
This array is then copied into the ATL buffer area.
Table 12
shows the ATL buffer area.
Step 5:
After copying data into the ATL buffer, the HC must be noti
fi
ed that the ATL
buffer is now full and ready to be processed. The ATL_Active bit of the
HcBufferStatus register must be set to logic 1 to inform the HC that the data in the
