... Philips Semiconductors 3-port physical layer interface 17.2 Using the PDI1394P21 with a non-P1394a link layer The PDI1394P21 implements the PHY-LLC interface specified in the P1394a Supplement. This interface is based upon the interface described in informative Annex J of IEEE Std 1394-1995, which is the interface used in older PHY devices. The PHY-LLC interface specified in P1394a is completely compatible with the older Annex J interface ...

... PRINCIPLES OF OPERATION The PDI1394P21 is designed to operate with an LLC such as the Philips Semiconductors PDI1394L11 or PDI1394L21. The following paragraphs describe the operation of the PHY-LLC interface. The interface to the LLC consists of the SYSCLK, CTL0–CTL1, D0–D7, LREQ, LPS, C/LKON, and /ISO terminals on the PDI1394P21 as shown in Figure 9 ...

... Philips Semiconductors 3-port physical layer interface LR0 LR1 18.1 LLC service request To request access to the bus, to read or write a PHY register control arbitration acceleration, the LLC sends a serial bit stream on the LREQ terminal as shown in Figure 10. The length of the stream will vary depending on the type of request as shown in Table 9 ...

Page 21

... Philips Semiconductors 3-port physical layer interface For a write register request, the length of the LREQ bit stream is 17 bits as shown in Table 14. Table 14. Write Register Request BIT(S) NAME DESCRIPTION 0 Start Bit Indicates the beginning of the transfer (always 1). 1–3 Request Type A 101 indicating that this is a write register request. 4– ...

... Philips Semiconductors 3-port physical layer interface 18.2 Status transfer A status transfer is initiated by the PHY when there is status information to be transferred to the LLC. The PHY waits until the interface is idle before starting the transfer. The transfer is initiated by the PHY asserting Status (01b) on the CTL terminals, along with the first two bits of status information on the D[0:1] terminals ...

Page 23

... Philips Semiconductors 3-port physical layer interface 18.3 Receive Whenever the PHY detects the data-prefix state on the serial bus, it initiates a receive operation by asserting Receive on the CTL terminals and a logic 1 on each of the D terminals (“data-on” indication). The PHY indicates the start of a packet by placing the speed code (encoded as shown in Table 17) on the D terminals, followed by packet data ...

Page 24

... Philips Semiconductors 3-port physical layer interface The sequence of events for a null packet reception is as follows: Receive operation initiated. The PHY indicates a receive operation by asserting receive on the CTL lines. Normally, the interface is idle when receive is asserted. However, the receive operation may interrupt a status transfer operation that is in progress so that the CTL lines may change from status to receive without an intervening idle ...

Page 25

... Philips Semiconductors 3-port physical layer interface 18.4 Transmit When the LLC issues a bus request through the LREQ terminal, the PHY arbitrates to gain control of the bus. If the PHY wins arbitration for the serial bus, the PHY-LLC interface bus is granted to the link by asserting the Grant state (11b) on the CTL terminals for one SYSCLK cycle, followed by Idle for one clock cycle ...

Page 26

... Philips Semiconductors 3-port physical layer interface The sequence of events for a cancelled/null packet transmission is as follows: Transmit operation initiated. PHY asserts grant on the CTL lines followed by idle to hand over control of the interface to the link. Optional Idle cycle. The link may assert at most one idle cycle preceding assertion of hold. This idle cycle is optional ...
