FCC1: UTOPIA Master Receive Address Bit 4
In the ATM UTOPIA master interface supported by FCC1 using
multiplexed polling, this is receive address bit 4.
FCC1: UTOPIA Slave Receive Address Bit 4
In the ATM UTOPIA slave interface supported by FCC1, this is
the receive address bit 4.
FCC1: UTOPIA Multi-PHY Master Receive Cell Available 3
Direct Polling
In the ATM UTOPIA master interface supported by FCC1 using
direct polling, RXCLAV3 is asserted by an external PHY when
one complete ATM cell is available for transfer.
SPI: Clock
The SPI interface comprises four signals: master out slave in
(SPIMOSI), master in slave out (SPIMISO), clock (SPICLK) and
select (SPISEL). The SPI can be configured as a slave or
master in single- or multiple-master environments. SPICLK is a
gated clock, active only during data transfers. Four
combinations of SPICLK phase and polarity can be configured.
When the SPI is a master, SPICLK is the clock output signal
that shifts received data in from SPIMISO and transmitted data
out to SPIMOSI.
Baud Rate Generator 2 Output
The CPM supports up to 8 BRGs. The BRGs can be used
internally to the MSC8101 and/or provide an output to one of
the 8 BRG pins.
FCC1: UTOPIA Receive Parity
In the ATM UTOPIA interface supported by FCC1, this is the
odd parity bit for RXD[0–7].
SPI: Master Output Slave Input
The SPI interface comprises our signals: master out slave in
(SPIMOSI), master in slave out (SPIMISO), clock (SPICLK) and
select (SPISEL). The SPI can be configured as a slave or
master in single- or multiple-master environments. When the
SPI is a slave, SPICLK is the clock input that shifts received
data in from SPIMOSI and transmitted data out through
SPIMISO.
