Hi,
Our customer designs the common board which both AM5728 and AM5718 can be equipped with.
In that case, please tell me how the following pins should process it.
An interrupt signal is in CS and the ODT pin of the DDR of unused (unusable), is there a problem?
AM5728 use pin
・AD17=Wakeup0
⇒gpio1_0
・AC16=Wakeup3
⇒sys_nirq1
・AB16=wakeup2
⇒sys_nirq2
・AC17=wakeup1
⇒gpio1_1
case AM5718
・AD17=Wakeup0
⇒gpio1_0
・AC16=Wakeup3
⇒sys_nirq1
・AB16=ddr1_csn1
⇒A signal of sys_nirq2 is input.
・AC17=ddr1_odt1
⇒A signal of gpio1_1 is input.
In addition, in Table 4-2 Ball Characteristics of the data sheet of AM5718, two functions become the same setting like following *.
Is it an error In writing?
AD17
Wakeup0
Wakeup0 :0
dcan1_rx :1
*gpio1_0 :14
*sys_nirq2 :14
Driver off :15
AC16
Wakeup3
Wakeup3 :0
sys_nirq1 :1
*gpio1_3 :14
*dcan2_rx: 14
Driver off :15
