(T-PDS screen example - in the case that CD332 is mounted on Slot 0 of Unit 0) Then, one input register, XW(n) is assigned to the CD332.
- Page 23 Data XW(n) Status IN3 The data of the CD332 can be read into the XW(n) register by using the Direct I/O instruction (FUN235). By executing the Direct I/O instruction, the interrupt flag (interrupt request) is reset to OFF internally, and at the same time, the status bits are reset to OFF inside the CD332.

CD332. And the I/O#1 is activated when the CD332 generates an interrupt. If two or more (up to 8) interrupt generation modules (CD332, etc.) are used, the interrupt programs are assigned sequentially from the module allocated closest to the T3 CPU. -

Especially, when using the high speed response mode, check this point carefully.
