CLOCK DIVISION FACTOR
RESERVED
Clock Division Factor
The value indicates clock division factor for
CLKOUT. The output frequency is
48 MHz/(N+1) where N is the Clock Division
Factor. The reset value is 11. This will
produce the output frequency of 4 MHz
which can then be programmed up (or down)
by the user. The minimum value is one giving
the range of frequency from 4 to 24 MHz.
The PDIUSBD11 design ensures no
glitching during frequency change. The
programmed value will not be changed by a
bus reset.
Data Flow Commands
Data flow commands are used to manage the data transmission
between the USB endpoints and the monitor. Much of the data flow
is initiated via an interrupt to the microcontroller. The microcontroller
utilizes these commands to access and determine whether the
endpoint FIFOs have valid data.

SV00829
This command indicates the origin of an interrupt. A ‘1’ indicates an
interrupt occurred at this endpoint. The bits are cleared by reading
the endpoint status register through the Read Endpoint Status
command.
After a bus reset, an interrupt will be generated and bit 6 of the
Interrupt Register Byte 2 will be ‘1’. The interrupt is internally cleared
by reading the interrupt register. A bus reset is completely identical
to the hardware reset through the RESET_N pin with the sole
difference of interrupt notification.

Select Endpoint
Command
Data
: 00-0Dh
: Optional Read 1 byte
The Select Endpoint command initializes an internal pointer to the
start of the Selected buffer. Optionally, this command can be
followed by a data read, which returns ‘0’ if the buffer is empty and
‘1’ if the buffer is full.
