• Manufacturer: Semtech Corporation

When the
is received, the UR7HCPXZ-P440
sets the following default
parameters: Incremental Stream
Mode, 1:1 scaling, report rate of
100 Hz, and disabled. It then
sends AAh to the host followed by
a device ID of 00h.
The host sends the Resend Last
Data Stream Command (FEh) when
it detects an error in any
UR7HCPXZ-P440 transmission.
The device then resends the last
output data packet to the host.
This transmission occurs after a
PixiPoint
before the host enables the
interface allowing the next
PixiPoint
The
Command (F6h)
device to its condition at power-up.
The
stops the device from transmitting
all reports. However, the mode
does not change; the PixiPoint
is still able to respond to
commands. If the Disable
Command is issued while the
device is transmitting a report, the
UR7HCPXZ-P440 immediately
stops the transmission and
disables itself.
