Miscellaneous

ALERT0

Alert 0

Interrupt input for connection to the local companion (UPD360/

UPD350) power delivery controller’s IRQ# signal.

DP2_VCONN1

I/O12

Port 2 VCONN1 enable. Active high signal.

0 = VCONN is turned off.

1 = VCONN is turned on. If DP2_VCONN1 is asserted and >3.0V is

not sensed on the CC1 line, a VCONN fault condition is detected.

Note 3-1

This pin can be left unused only if Port 2 is

disabled or reconfigured to operate as a legacy

Type-A port via OTP/SMBus/SPI configuration.
