Host requests
The ISP1122A handles all standard USB requests from the host via control
endpoint 0. The control endpoint can handle a maximum of 64 bytes per transfer.
Remark:
Please note that the USB data transmission order is Least Significant Bit
(LSB) first. In the following tables multi-byte variables are displayed least significant
byte first.
9.1 Standard requests
Table 7
shows the supported standard USB requests. Some requests are explicitly
unsupported. All other requests will be responded with a STALL packet.
