Hi!
I'm making a project with microcontroller 8051 connecting to ISD4002 chipcorder.
the project including remote control using NEC protocol, ISD4002 chip with speaker and microphone, all connected and manage by the 8051. (nxp p89v51rd2).
my problem is that when i'm sending the spi code to the 4002 of recording or playing it's generate interrupt signal at the middle of the command even without waiting to the action command ends.
if someone know the reason for the problem I'll be greatfull to hear it.
have a nice day,
regards,
Zvika
