Hi all:
I would like to know if anybody can help me with a problem with the
PIC16C74. I am using the slave port D of this device, but when I write
to it an interruption is generated and the interrupt vector is modified
and the interrupt flags are modified also, and as I am using also
interrupts for the serial port and port B I get all confused because I
am not sure which device generated the interruption.

If anybody has experience using this PIC or has experienced similar
problems, please help me.

Yuri
