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

Pin No.	Signal Name	Attribute	Description


B2	ATMTCAb (PA30)	I/O, T.S.	ATM Transmit Cell Available (H). When this signal is asserted
			(High), while the ATM port is enabled, it indicates that the transmit
			FIFO of the PM5350 is empty and ready to except a new cell.
			When negated, it may show either that the transmit FIFO is Full or
			close to Full, depending on PM5350 internal programming.
			When the ATM port is disabled, this line may be used for any
			available function of PA30.

B3	ATMTSOC (PA29)	I/O, T.S.	ATM Transmit Start Of Cell (H). When this signal is asserted
			(High) by the MSC8101, while the ATM port is enabled, it
			indicates to the PM5350 the start of a new ATM cell over
			ATMTXD(7:0), i.e., the 1’st octet is present there.
			When the ATM port is disabled, this line may be used for any
			available function of PA29.

B4	ATMRXENb (PA28)	I/O, T.S.	ATM Receive Enable (L). When this signal is asserted (Low),
			while the ATM port is enabled and ATMRFCLKb goes high, on
			octet of data is available at the PM5350’s ATMRXD(7:0) lines.
			When negated while ATMRFCLK goes high data on
			ATMRXD(7:0) is invalid, however driven.
			When the ATM port is disabled, this line may be used for any
			available function for PA28.

B5	ATMRSOC (PA27)	I/O, T.S.	ATM Receive Start Of Cell (H). When this signal is asserted
			(High), while the ATM port is enabled, it indicates, that the 1’st
			octet of data for the received cell is available at the PM5350’s
			ATMRXD(7:0) lines. This line is updated over the rising edge of
			ATMRFCLK.
			When the ATM port is disabled, this line is tristated and may be
			used for any available function for PA27.

B6	ATMRCA (PA26)	I/O, T.S.	ATM Receive Cell Available (H). When this signal is asserted
			(High), while the ATM port is enabled and ATMRFCLK goes high,
			it indicates that the PM5350’s receive FIFO is either full or that
			there are 4 empty bytes left in it - PM5350 internal programming
			dependent.
			When the ATM port is disabled, this line is tristated and may be
			used for any available function of PA26.

B7	ATMTXD0 (PA25)	I/O, T.S.	ATM Transmit Data (7c:0). When the ATM port is enabled, this
			bus carries the ATM cell octets, written to the PM5350’s transmit
B8	ATMTXD1 (PA24)
B8	ATMTXD1 (PA24)		FIFO. This bus is considered valid only when ATMTXENb is
			asserted and are sampled on the rising edge of ATMTFCLK.
B9	ATMTXD2 (PA23)		asserted and are sampled on the rising edge of ATMTFCLK.
B9	ATMTXD2 (PA23)		When the ATM port is disabled, these lines may be used for any

B10	ATMTXD3 (PA22)		available respective function.

B11	ATMTXD4 (PA21)

B12	ATMTXD5 (PA20)

B13	ATMTXD6 (PA19)

B14	ATMTXD7 (PA18)
