Data
The Set Mode command is followed by two data writes. The first
byte contains the configuration byte values. The second byte is the
clock division factor byte.

A ‘1’ indicates that a remote wakeup feature
is ON. Bus reset will set this bit to ‘1’.
A ‘1’ indicates that CLKOUT will not switch
to LazyClock. A ‘0’ indicates that the
CLKOUT switches to LazyClock 1ms after
the Suspend pin goes high. LazyClock
frequency is 30 kHz ( 40%). The
programmed value will not be changed by a
bus reset.
A ‘1’ indicates that the internal clocks and
PLL are always running even during
Suspend state. A ‘0’ indicates that the
internal clock, crystal oscillator and PLL are
stopped whenever not needed. To meet the
strict Suspend current requirement, this bit
needs to be set to ‘0’. The programmed
value will not be changed by a bus reset.
A ‘1’ indicates that all errors and “NAKing”
are reported and a ‘0’ indicates that only OK
and babbling are reported. The programmed
value will not be changed by a bus reset.
A ‘1’ indicates that the upstream pull-up
resistor will be connected if VBUS is
available. A ‘0’ means that the upstream
resistor will not be connected. The
programmed value will not be changed by a
bus reset.

A ‘1’ indicates that downstream resistors are
connected. A ‘0’ means that downstream
resistors are not connected. The

A ‘1’ indicates that GoodLink
NOT blink when there is traffic. Leave this bit
at ‘0’ to achieve blinking LEDs. The
programmed value will not be changed by a
bus reset.
A ‘1’ indicates single embedded function
mode. A ‘0’ indicates multiple (3) embedded
function mode. See endpoint descriptions for
details. The programmed value will not be
changed by a bus reset.
CLKOUT. The output frequency is
48 MHz/(N+1) where N is the Clock Division
Factor. When the 48MHz input crystal
frequency is selected, the reset value is 3.
This will give a default output frequency at
CLKOUT pin of 12 MHz, thus maintaining
backward compatibility to the PDIUSBH11.
When the 12 MHz input crystal frequency is
selected, the reset value is 11. This will
produce the lowest output frequency of 4
MHz which can then be programmed up by
the user. The PDIUSBH11A design ensures
no glitching during frequency change. The
programmed value will not be changed by a
bus reset.
