3.2.13 RSID Register: Receive SID
SMSC TMC2072
“00h” should be specified for the higher bytes. Readable value from this register is the prior write
command.
03h: Send command
This command instructs the CircLink to start sending. After issuing the send command, an actual sending
is started upon receipt of token to the node. In continuous send mode (TXM = 1, RTO = 0) or in remote
buffer sending mode, an automatic send operation repeats whenever a node receives the token after the
first one time command has been issued.
In free format send mode (TXM = 0) or the remote buffer send mode, a send command must be issued
each time when in single send mode (TXM = 1, RTO =1).
01h: Sending cancellation command
This command cancels the prior send command . After cancellation, the TA bit is set to 1. If this command
is issued before the node receives the token, cancellation of the send is possible.
It is necessary to confirm TA=1 because the cancellation is actually executed when the token arrives.
In continuous send mode (TXM = 1, RTO = 0) in the remote buffer send mode, continuous send operation
can be stopped. (To restart, re-send command is necessary.)
09h: NXTIDERR clear command
This command clears the NXTIDERR bit in COMR1 (Diagnostic register) .
0Ah: WARTERR clear command
This command instructs initialization and start of the warning timer function. In addition, this command
clears the WARTERR bit and the INTSTA register as well as all receive flag in the page that is set to the
remote buffer mode.
0Eh: POR, EXCNAK clear command
This command clears the POR bit in COMR0 (status register) and the EXCNAK bit in COMR1 (diagnostic
register). Cancellation of either of two bits is unavailable.
16h: RECON clear command
This command clears the RECON bit in COMR0 (status register).
1Eh: Concurrent operation of POR, EXCNAK clear and RECON clear command
These commands clear all POR, EXCNAK, and RECON bits.
