TABLE B1-3. P2 - CPM Expansion - Interconnect Signals

Pin No.	Signal Name	Attribute	Description


D5	CLK5 (PC27)	I/O, T.S.	Clock 5 input. When TDMB is enabled this pin is an input clock.
			When TDMB port is disabled this line may be used for any
			available function of PC27 Port C.

D6	ATMFCLK (PC26)	I/O, T.S.	ATM Transmit FIFO Clock. Upon the rising edge of this clock
			(driven by the MSC8101), while the ATM port is enabled, the cell
			octets are written to the PM5350’s transmit FIFO. This clock
			samples ATMTXD(7:0), ATMTXPTY, ATMTXENb and ATMTSOC.
			When the ATM port is disabled, this line may be used for any
			available function of PC26.

D7	DACK2b(PC25)	I/O, T.S.	DMA channel 2 data acknowledge. Output from DMA port. Using
			for external DMA tool. When the DMA port is disabled, this line
			may be used for any available function of PC25.

D8	DREQ2b(PC24)	I/O, T.S.	DMA channel 2 data request acknowledge. This signal is
			asserted by the DMA, indicating that the DMA has sampled the
			peripheral request. Using for external DMA tool. When the DMA
			port is disabled, this line may be used for any available function of
			PC24.

D9	DACK1b(PC23)	I/O, T.S.	DMA channel 1 data acknowledge. Output from DMA port. Using
			for external DMA tool. When the DMA port is disabled, this line
			may be used for any available function of PC23.

D10	DREQ1b(PC22)	I/O, T.S.	DMA channel 1 data request acknowledge. This signal is
			asserted by the DMA, indicating that the DMA has sampled the
			peripheral request. Using for external DMA tool. When the DMA
			port is disabled, this line may be used for any available function of
			PC22.

D11	N.C.	-	Not connected.

D14

D15

D16

D17	PC15	I/O, T.S.	MSC8101’s Port C15 Parallel I/O line. May be used to any of its
			available functions.

D18	SCC1CDb (PC14)	I/O, T.S.	RS232 Port 1 Carrier Detect (L). Connected via RS232
			transceiver to RS232 DTR1b input, allowing detection of a
			connected terminal to this port. This line is simply a I/O input line
			to the MSC8101.
			When RS232 Port 1 is disabled, this line is tristated and may be
			used for any available function of PC14.

D19	FETHMDC (PC13)	I/O, T.S.	Fast-Ethernet Port Management Data Clock. This slow clock (S/
			W generated) qualifies the management data I/O to read / write
			the LXT970’s internal registers.
			When the Ethernet port is disabled, this line may be used for any
			available function of PC13.
