Hello,

 

I know some pins for example CMOS inputs, open-drain outputs shouldn't be left floating except some special cases. Even If you are not using it.

 

There are some pins that I am not sure If I can leave them floating or not. I want to be sure that I can leave the following unused pins floating. Could anybody check please?

 

D1_MDM8

D1_MDQS8

D1_MDQS8_B

D1_MCS[1-3]_B

D1_MCKE[1-3]

D1_MCK[1-5]

D1_MCK[1-5]_B

The same pins of Memory Controller2

EVT[0-8]_B

SDHC_CLK

TSEC_1588_ALARM_OUT1

TSEC_1588_CLK_OUT

TSEC_1588_PULSE_OUT1

EMI1_MDC

EMI2_MDC

EMI2_MDIO

MDVAL

MSRCID0
