FCC1: UTOPIA Receive Data Bit 2
In the ATM UTOPIA interface supported by FCC1. The
MSC8103 inputs ATM cell octets (UTOPIA interface data)
on RXD[0–7]. RXD7 is the most significant bit. RXD0 is the
least significant bit. A cell is 53 bytes. To support Multi-PHY
configurations, RXD[0–7] is tri-stated, enabled only when
RXENB is asserted.
Module Serial Number Bit 3
MSNUM[0-4] of is the sub-block code of the current
peripheral controller using SDMA. MSNUM5 indicates
which section, transmit (0) or receive (1), is active during
the transfer.
FCC1: UTOPIA RX Receive Data Bit 1
In the ATM UTOPIA interface supported by FCC1. The
MSC8103 inputs ATM cell octets (UTOPIA interface data)
on RXD[0–7]. RXD7 is the most significant bit. RXD0 is the
least significant bit. A cell is 53 bytes. To support Multi-PHY
configurations, RXD[0–7] is tri-stated, enabled only when
RXENB is asserted.
Module Serial Number Bit 4
MSNUM[0–4] of is the sub-block code of the current
peripheral controller using SDMA. MSNUM5 indicates
which section, transmit (0) or receive (1) is active during the
transfer.
FCC1: UTOPIA RX Receive Data Bit 0
In the ATM UTOPIA interface supported by FCC1. The
MSC8103 inputs ATM cell octets (UTOPIA interface data)
on RXD[0–7]. RXD7 is the most significant bit. RXD0 is the
least significant bit. A cell is 53 bytes. To support Multi-PHY
configurations, RXD[0–7] is tri-stated, enabled only when
RXENB is asserted.
Module Serial Number Bit 5
MSNUM[0–4] of is the sub-block code of the current
peripheral controller using SDMA. MSNUM5 indicates
which section, transmit (0) or receive (1), is active during
the transfer.
SMC2: Serial Management Transmit Data
Supported by SMC2. The SMC interface consists of
SMTXD, SMRXD, SMSYN, and a clock. Not all signals are
used for all applications. SMCs are full-duplex ports that
supports three protocols or modes: UART, transparent, or
general-circuit interface (GCI). See also PC15.
Time-Division Multiplexing A1: Layer 1 Transmit Data
Bit 0
In the TDMA1 interface supported by SI1. L1TXD3 is the
most significant bit. L1TXD0 is the least significant bit in
nibble mode. TDMA1 transmits nibble data out L1TXD[0–3].
