Clock and Other Pins

Table 6. Clock and Other Pins

Symbol Type Pin No Description

XI I 25 40MHz OSC Input.

Input of 40MHz Crystal clock reference.

XO O 26 Output of 40MHz Crystal clock reference.

ISOLATIONn I 48 This pin can externally shutdown 8191SE without extra power switch. This pin can

also support WLAN Radio off function with host interface remaining connected.

VAUXEN/EESK I 62 Weakly pull high at power on to indicate the presence of the auxiliary power on the

mainboard. Otherwise, this is for EEPROM autoload.

GPIO0/WLAN_

ACT

I/O 29 There are 8 General Purpose Input/Output pins. Some are used for power-on latch and

Bluetooth coexistence, and also EEPROM purposes.

The WLAN_ACT signal indicates when WLAN is either transmitting or receiving in

the 2.4GHz ISM band.

GPIO1/WLAN_R

I/O 30 Wireless LAN RX activity indicator.

GPIO2/BT_STAT

I/O 31 The BTSTAT signal indicates when normal Bluetooth packets are being transmitted or

received.

GPIO3/BT_PRI I/O 32 Left not connected if the EEPROM in use is 93C46.

The BTPRI signal indicates when a high priority Bluetooth packet is being transmitted

or received.

GPIO4 I/O 56 GPIO4.

GPIO5 I/O 57 GPIO5.

GPIO6/EEDO I/O 60 EEPROM interface EEDO signal.

GPIO7/EEDI I/O 61 EEPROM interface EEDI signal.
