Bit
15
0 (00): No communication cartridges
1 (01): RS-232C communication cartridge
2 (10): RS-485 communication cartridge
3 (11): Bluetooth communication cartridge
■ D8031: Optional Device Connection Information
Optional device connection information is written to this register.
The allocation of bits in the device (bit assignment) is as follows.
Bit
15
0: No optional device
1: Optional device is connected
■ D8032 to D8035, D8214, D8215: Interrupt Input Jump Destination Label No.
Jump destination label numbers for interrupt inputs are written to these registers. When using interrupt inputs, write the label
number that corresponds to the special data register that has been allocated to the interrupt input. For details on interrupt
inputs, see "Interrupt Input" on page 5-37.
D8032 = I1
D8033 = I3
D8034 = I4
D8035 = I6
D8214 = I7
D8215 = I0
■ D8036: Timer Interrupt Jump Destination Label No.
The jump destination label number when the timer interrupt occurs is written to this register. When using the timer interrupt,
store the corresponding label number.
For details on the timer interrupt, see "Timer Interrupt" on page 5-48.
