O

CPU Core Interrupt. When enabled, this signal provides

AFD#/DSTRB#+

 

 

 

for monitoring of the internal GX1 core INTR signal for

TFTD2

 

 

 

debug purposes. To enable, pull up FPCI_MON (ball A4).

GX1 core. When enabled, this signal provides for moni-

 

 

 

 

toring of the internal GX1 core SMI# signal for debug pur-

 

 

 

 

poses. To enable, pull up FPCI_MON (ball A4).
