Flag Descriptions
nPOSTR
The nPOSTR outputs a pulse after the OUTPUT DATA packet is received and the state of OUTPUT
PORT is stabled. As the delay time from the settling of OUTPUT PORT state to the output of strobe pulse,
one of two delay times is selectable using the POSTRDLY bit that is configured through network.
nTXDONE
nNSTCOUT
NSTUNLOC
nTKN2ME
nRCNERR
nPOSTR
OUTPUT DATA packet was received.
The INITIALIZE OUTPUT PORT command was received when POSTRMD = 0 had been configured
through network.
Dropped from network due to EMGYMD = 1 (MYRECON asserted) when POSTRMD = 0 had been
configured through network.

Controller
The strobe pulse for the OUTPUT PORT (active low). This can be used as the strobe
signal for such as an external DA converter (see the examples of application circuits in the
section of the Appendix). The following events assert nPOSTR:
The pulse that indicates the completion of transmitting the INPUT DATA packet (active
low). The pulse Level Width is Tdr (= transmission rate period). This can be used as the
trigger signal for such as an external AD converter (see the example of application circuits
in the section of the Appendix).
NST carry pulse (active low or clock). For detail information, see the section of NST.
The output flag that indicates the synchronization status between own and clock master’s
NSTs (active high). The asynchronous state (unlocked state) causes High level.
detail information, see the section of NST.
The pulse that indicates that own token was received (active low). The pulse Level Width
is Tdr ( = transmission rate period).
The output flags that indicates network error (active low).
This is asserted in the event of dropping from network (MYRECON asserted), expiring idle
timer or token retry and it is reset upon receiving own token.
POSTRDLY=0: Tx X (11 to 14)
