number of transfers to be performed. The actual transfer count will be in register 0x05 and 0x06
depending the type of operation.
Interrupt Transfer
USB Endpoint 5 is used for the interrupt transfer on the Tiger560. The polling interval is 1ms.
Each time polling occurs, 2 bytes of data will be transferred from the Tiger 560 to the host. The
first byte of data is the value of AUX pins current state. The second byte is the value of specified
source. Register 0x18 is defined as the location for this byte. Only the external PIB will be used
for the polling. Setting bits 7 and 6 in register 0x18 to 1 will enable the PIB interrupt status polling.
The polling operation will not conflict with any vendor command because the polling will be
performed in every USB SOF (Start-Of-Frame) package. Byte one will show the current status of
any interrupt line connected to the AUX pins and byte two will be the value of the interrupt status
of the peripheral (external) device.
