CS8900

Terms Specific to the CS8900 (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 CS8900 used to conserve power. When in Standby mode, the CS8900 can be

awakened either by 10BASE-T activity or host command.

Suspend

A feature of the CS8900 used to conserve power. When in Suspend mode, the CS8900 can be

awakened only by host command.

Transfer

The term "transfer" refers to moving frame data across the ISA bus to or from the CS8900.

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.
