Output of Crystal Clock Reference

25 This Pin can Externally Shutdown RTL8189ETV without Extra Power

Switch

29 .General Purpose Input/Output Pin

Trap function: weak pull low to enable integrated switching regulator;

weak pull high to enable integrated linear regulator

28 General Purpose Input/Output Pin

26 General Purpose Input/Output Pin

CLK_REQ pin: This also can be configured as CLK_REQ pin, which is

used by 8189ETV to request Crystal Clock from the host.

32 General Purpose Input/Output Pin,

Trap function: weak pull low to enable RTL8189ETV to enter normal

operation mode.
