S3F80JB

Important Note

 

 

2.2 FOR NORMAL OPERATING MODE

The S3F80JB/9 is needed to nRESET pin = “1(VDD)” & TEST pin = “0(GND)”

P1.4~1.7

When nRESET pin = “1(VDD)” & TEST pin = “0(GND)”

In the Figure 2, because TEST signal is low(Logic level 0), “outdis” and “data” signal is same to MUX “0” signal. So, in normal operation, port1.7 doesn’t occurred to toggling phenomenon because of SDAT changing
