7.2.2
Setting non-priority of transmission to the AJ71C24 with the half-duplex transmission
The following shows how to set the AJ71 C24 t o discontinue transmission when
the AJ71C24 and an external device (using half-duplex transmission) have
begun transmitting data to each other sim&aneousiy
(1) Setting "half-duplex transmission", "non-priority", and "not resend":

1: Half-duplex transmission
.Set
bits b l to b15 of address 1OFH to either 0 or 1. (The AJ71C24 will
ignore the settings.)
(2) Priority setting when transmission has begun simultaneously

Set bits b l to b15 of address 11 1 H either to 0 or 1. (The AJ71 C24 will
ignore the settings.)
xampleI
The CD terminal check is set to "Enabled".
Half-duplex transmission is used and the
non-priority of transmission and "not resend" are set. (Send wait time: 300 msec) (AJ71C24
I10 addresses: 80 to
9F)
(Sequence Program)
Write "1" to buffer memory address 10FH.
Write "3" to buffer memory address 110H.
Leave the setting of buffer memory
addresses lOBH and 111H for defaults.
