be performed through the SMBus interface, or permanently via OTP. Refer to the Protouch
MPT User Manual for additional information.
Note 3.3
If using the local power detect function (LOCAL_PWR pin), the NON_REM[1:0]
configuration straps cannot be used to configure the non-removable state of the USB ports.
In this case, the non-removable state of the ports must be configured in internal device
registers via the Protouch tool or SMBus.
Note 3.4
Configuration strap values are latched on Power-On Reset (POR) and the rising edge of
RESET_N (external chip reset). Configuration straps are identified by an underlined
symbol name. Signals that function as configuration straps must be augmented with an
external resistor when connected to a load. Refer to Section 6.3, "Device Configuration
Straps," on page 29 for additional information.
