Serial Interface 2: Strobe 1

The MSC8103 time-slot assigner supports up to four strobe outputs that

can be asserted on a bit or byte basis. The strobe outputs are useful for

interfacing to other devices that do not support the multiplexed interface or

for enabling/disabling three-state I/O buffers in a multiple-transmitter

architecture. These strobes can also generate output wave forms for such

applications as stepper-motor control.

FCC1: Clear To Send

In the standard modem interface signals supported by FCC1 (RTS, CTS,

and CD). CTS is asynchronous with the data.

FCC1: UTOPIA Multi-PHY Master Transmit Address Bit 2

This is master transmit address bit 2.

FCC1: UTOPIA Multi-PHY Slave Transmit Address Bit 2

This is slave transmit address bit 2.

FCC1: UTOPIA Multi-PHY Master Transmit Cell Available 1 Direct

Polling

Asserted by an external UTOPIA slave PHY to indicate that it can accept

one complete ATM cell.

Serial Interface 2: Layer 1 Strobe 2

The MSC8103 time-slot assigner supports up to four strobe outputs that

can be asserted on a bit or byte basis. The strobe outputs are useful for

interfacing to other devices that do not support the multiplexed interface or

for enabling/disabling three-state I/O buffers in a multiple-transmitter

architecture. These strobes can also generate output wave forms for such

applications as stepper-motor control.

FCC1: Carrier Detect

In the standard modem interface signals supported by FCC1 (RTS, CTS,

and CD). CD is an input asynchronous with the data.

FCC1: UTOPIA Multi-PHY Master Receive Address Bit 2

This is master receive address bit 2.

FCC1: UTOPIA Slave Receive Address Bit 2

This is slave receive address bit 2.

FCC1: UTOPIA Multi-PHY Master Receive Cell Available 1 Direct

Polling

Asserted by an external PHY when one complete ATM cell is available for

transfer.
