Description
15
DisableSuspend_Wakeup This bit when set to logic 1 disables the function of the
D_SUSPEND/D_WAKEUP and
H_SUSPEND/H_WAKEUP pins. Therefore, these pins
will always remain HIGH and pulling them LOW does
not wake up the HC and the DC.

GlobalPowerDown
Set this bit to logic 1 to reduce power consumption of
the OTG ATX in the suspend mode.
ConnectPullDown_DS2
0 — disconnect built-in pull-down resistors on H_DM2
and H_DP2
1 — connect built-in pull-down resistors on H_DM2
and H_DP2 for the downstream port 2
Remark: Port 2 is always used as a host port.
