Aironet Wireless Communications, Inc. 7-67 Confidential and Proprietary
packet, or to transmit a packet, the host must first awaken the PC4500/4800 by setting EvAck.Awaken.
This must be done twice without any delays:
void awaken_4500(void)
{
push_interrupt_enable_state();
disable_interrupts();
OUT4500(EVACK, EV_AWAKEN); // first awakens
OUT4500(EVACK, EV_AWAKEN); // second does actual write
pop_interrupt_enable_state();
}
After some delay, which could be 50 milliseconds or more, the PC4500/4800 will issue an EvStat.Awake
event. The host should then acknowledge this (EvAck.Awake) and proceed to processing the actual event,
or transmitting the required packet.
