For a 32-bit operation, the default wake-up counter value is 10 s. For a 16-bit operation, the wake-up counter value is 50 ms. In the
16-bit operation, read and write back the same value on initialization.

Power-Down Control register (address 0354h) bit description
Description
Port 2 Pull-Down: Controls port 2 pull-down resistors.
0 — Port 2 internal pull-down resistors are not connected.
1 — Port 2 internal pull-down resistors are connected.
V
0 — V
1 — V
reserved; write reset value
Bias Circuits Powered: Controls the power to internal bias circuits.
0 — Internal bias circuits are not powered in suspend.
1 — Internal bias circuits are powered in suspend.
V
SAF1761
0 — Internal regulators are normally powered in suspend.
1 — Internal regulators switch to low power mode (in suspend mode).
OC3_N Powered: Controls the powering of the overcurrent detection circuitry for port 3.
0 — Overcurrent detection is powered-on or enabled during suspend.
1 — Overcurrent detection is powered-off or disabled during suspend.
This may be useful when connecting a faulty device while the system is in standby.
OC2_N Powered: Controls the powering of the overcurrent detection circuitry for port 2.
0 — Overcurrent detection is powered-on or enabled during suspend.
1 — Overcurrent detection is powered-off or disabled during suspend.
This may be useful when connecting a faulty device while the system is in standby.
OC1_N Powered: Controls the powering of the overcurrent detection circuitry for port 1.
0 — Overcurrent detection is powered-on or enabled during suspend.
1 — Overcurrent detection is powered-off or disabled during suspend.
This may be useful when connecting a faulty device while the system is in standby.
Host Controller Clock Enabled: Controls internal clocks during suspend.
0 — Clocks are disabled during suspend. This is the default value. Only the LazyClock of
100 kHz
during suspend, CLKREADY IRQ will be generated when all clocks are running stable.
1 — All clocks are enabled even in suspend.

detector is not powered or disabled in suspend.
40 % will be left running in suspend if this bit is logic 0. If clocks are stopped
