Terms Specific to the CS8920A (continued)
PacketPage
A unified, highly-efficient method of controlling and getting status of a peripheral controller in
I/O or Memory space.
Standby
A feature of the CS8920A used to conserve power. When in Standby mode, the CS8920A can
be awakened either by 10BASE-T activity or host command.
StreamTransfer
A method used to significantly reduce the number of interrupts to the host processor during
block data transfers (Patent Pending).
Suspend
A feature of the CS8920A used to conserve power. When in Suspend mode, the CS8920A can
be awakened only by host command.
Transfer
The term "transfer" refers to moving frame data across the ISA bus to or from the CS8920A.
Transmit Request
A Transmit Request is issued by the host to initiate the start of a new packet transmission. A
Transmit Request consists of the following three steps in exactly the order shown:
1. The host writes a Transmit Command to the TxCMD register (PacketPage base + 0144h).
2.
The host writes the transmit frame’s length to the TxLength register (PacketPage base +
0146h).
3. The host reads BusST (Register 18) to see in the Rdy4TxNOW bit (Bit 8) is set.
WakeUp Frame
A specific Ethernet frame that enables an NIC to signal the PC power management to power
up the PC.
