Pin
1
Function
TXPE
Description
Input from the external network processor. The rising edge of TX PE
places the transmitter into an active state. The falling edge of TX PE
indicates the end of transmission.
When active (value '1'), the receiver is powered up and CCA circuitry is
active.
Master clock. This should be a 44MHz for IEEE802.11b and is used to
generate other internally used clocks.
Indicates that the chip is ready to accept data from the MAC for Tx.
