We are designing a 8bit ISA card using PIC16C65A. The reset line
and IRQ2 lines does not work. We have portB,1 program to send a high
when read happens the line goes high for 500ns but system level does
not see an IRQ. Same problem with the reset, We send a software reset
using address 394 which decodes in our EPLD and sends a low for 500ns but
still PIC does not resets. Putting a manual switch on the reset
works fine. We have tried different analog circuits but they are two
Please let me know if you have any ideas. Thank you very much.
