(7) In the case of interrupt outputs
The following shows an example of an interrupt output when data are written to the interrupt output devices (D13
and D14).
(Assuming that "3139
H
" is written to D13 and "AA55
H
" to D14.)
POINT POINT POINT
Interrupt output
• To disable the interrupt output, turn ON SM52 (interrupt code output disable flag). ( 61.4.6 SM devices)
• To issue interrupts, set the data length to "8 bits" at "Communication Detail Settings".
( 61.6.1 Setting communication interface (Communication settings))
• When "7 bits" is set, the MSB (8th bit) is ignored. (Example: FF
H
7F
