MELSEGA
If
the
roceive
data kngth exceed8 the no-protocol mode receive buffer memory rize, the data
io
proceued
aa
deroribed below.
(1) When the receive oomploted code
la
umd:
If
the AJ71C24 receiver data that exceed8 the receive area rite,
tt
turnr
ON
the received
data read requoat rignal Xnl when data equivalent
to
the receive area rize ha8 been
received.
Reading the remaining data
ir
enabled at
tho
time
the
aoquence program turnr the receive
data read completed signal
Y(n+l)l
ON.
There step8 are repeated until the receive completed code
ir
received.
Set the recoive area
rite
80
that 'recdve-completion data length" is
1088
than 'no-protocol
mode receive buffer memory
rite".
Example:
To
receive 150 word8
of
data while receive area
it
set
at
80H to FFH (default).
(2) When receive completion data length
ir
ured:
tf
the receive completion data length
ir
rot
greater than the receive area rite,
the
no-
protocol receive buffer memory
site
(default: 127 wordr) which
is
ret at buffer memory
addrur 107H is taken a8 the receive completion data length.
Set
the receive area
rim
80
that 'receive completion data length' is
1088
than 'no-protocol
mode receive buffer memory
size".
Example:
To
receive 150 word8
of
data while receive area
ir
ret at 80H to FFH (default retting).
