TACKEN (DS30292B, PIC16F87X datasheet) This signal goes low whenever someone in the documentation department does a global search-and-replace on the ACKEN signal and hits a few extra words. The signal will be returned high whenever the paragraph(s) are read, indicating some newbie pic programmer is actually reading the data sheets. "Bus control can be TACKEN by setting the P bit...."
