43
PD#
IN
Enter /Exit Power Down.
0 = Power Down, 1 = normal operation.
44
RESTORE#
I/O
Open Drain I/O. As an input it restores the PLL's to power up default state. As an output, this signal
is driven low when the internal watchdog hardware timer expires. It is cleared when the internal
watchdog hardware timer is reset or disabled. The input is falling edge triggered.
0 = Restore Settings, 1 = normal operation.
45
GNDHTT
PWR
Ground pin for the HTT outputs
46
HTT0C_LPRS/66M
OUT
Complementary signal of low-power differential push-pull hypertransport clock with integrated series
resistor. (no 50ohm shunt resistor to GND and no 33 ohm series resistor needed) / 3.3V single ended
66MHz hyper transport clock
47
HTT0T_LPRS/66M
OUT
True signal of low-power differential push-pull hypertransport clock with integrated series resistor. (no
50ohm shunt resistor to GND and no 33 ohm series resistor needed) / 3.3V single ended 66MHz
hyper transport clock
48
VDDHTT
PWR
