CONFIGURATION SELECTION

The CFG_SEL0 and CFG_SEL1(UPD360-A/UPD360-B only) pins share the comparator with VBUS as shown in

Figure 9-3. Each CFG_SELx pin is connected to a resistor divider, typically pulled up to VDDIO. After a system level

reset (POR, RESET_N, Software Reset), both CFG_SELx pins are automatically sampled to configure the device. The

CFG_SELx Match Registers (CFG_SELx_MATCH) are updated automatically and the device configures itself accord-

ingly if standalone mode is detected.

The various resistor settings for the CFG_SEL0 and CFG_SEL1 pins are detailed in Table 9-7 and Table 9-8, respec-

tively.

Note:

For additional information on device resets, refer to Section 7.7, "Reset Operation," on page 34.

Description

CFG_SEL0_MATCH

GND

Standalone DFP / USB58xx/USB59xx Companion DFP

Device operates in standalone DFP mode (UPD360-A/UPD360-B only) for

applications where an I2C connection to the host is not be present.

The PWR_CAPx pins are used to select the USB Type-C™ current provided.
