2.5.3
NOTES: Limitations on the specifiable values for CP.
Revision 0.1 (06-07-07)
Packet Data Structure
PS = [1:0] = Example of 11 (32-byte mode)
SID: Source-ID (Source node ID)
DID: Destination-ID (Destination node ID) : DID=0 means the broadcast packet.
CP: Continuation pointer
Write the value (Page size - N) for sending N-byte data. That is, it indicates the top position of data in the
page. The example shows the value is 1Ah (32 - 6 bytes = 26 bytes = 1Ah).
32B Mode (PS [1:0] = 11)
64B Mode (PS [1:0] = 10)
128B Mode (PS [1:0] = 01)
256B Mode (PS [1:0] = 00)
If a packet is sent with CP other than the specified value the destination node rejects the packet, and the
session closes with a sending error (TXERR). Simultaneously the CP error (CPERR) flag of the EC status
register is set, which can issue an interrupt. The error flag, however, means a setup or CP specification
error to the CircLink, and does not indicate a network error.
Sender:
Sending error (TXERR) and CP error (CPERR) flags are set and a token is passed to the next node. Since
TA flag is reset to 1 except in the remote buffer mode (TXM = 1) as well as the continuous send mode
(RTO = 0), a send command must be issued for re-sending.
