2.5 Interrupt Operation All P2C0, P5C0, P8C0 and P11C0 can be us ed as interrupt signal sources. Refer to Sec. 2.1 & Sec. 2.7 for P2C0/P5C0/P8C0/P11C0 location. The interrupt of OME- PIO-D96 is level-trigger & Active_High . The interrupt signal can be inverted or non-inverted programmable.
2.5.1 Interrupt Block Diagram of OME-PIO-D96 INT_CHAN_0 INT_CHAN_1 INT_CHAN_2 INT_CHAN_3 INT Level_trigger initial_low active_high The interrupt output signal of OME-PIO-D96, INT, is Level_trigger & Active_Low . If the INT generate a low-pulse, the OME-PIO-D96 will interrupt the PC only once.
2.5.2 INT_CHAN_0/1/2/3 INT_CHAN_0 (1/2/3) Inverted/Noninverted select INV0(1/2/3) Enable/Disable select EN0(1/2/3) P2C0(P5C0/P8C0/P11C0) The INT_CHAN_0(1/2/3) must be fixed in low level state normally and generated a high_pulse to interrupt the PC. The EN0 (EN1/EN2/EN3) can be used to enable/disable the INT_CHAN_0(1/2/3) as follows: (Refer to Sec.
2.5.3 Initial_high, active_low Interrupt source If the P2C0 is an initial_high, active_lo w signal, the interrupt service routine should use INV0 to invert or not to i nvert the P2C0 for high_pulse generation as follows: (Refer to DEMO4.
2.5.4 Initial_low, active_high Interrupt source If the P2C0 is an initial_low, active_hi gh signal, the interrupt service routine should use INV0 to invert or not to i nvert the P2C0 for high_pulse generation as follows: (Refer to DEMO3.
2. 5 .5 Muliti Interrupt Source Assume: P2C0 is initial Low, active High, P5C0 is initial High, active Low P8C0 is initial Low, active High P11C0 is initial High, active Low as follows: P5C0 P2C0 P8C0 P11C0 P2C0 & P5C0 are return to normal at the same time.
