AM2431: PADCONFIG of MCU_PORz

Part Number: AM2431
Other Parts Discussed in Thread: SYSCONFIG

I am looking at the AM2431 TRM(SPRUIM2F).
I have a question about the MCU_PADCONFIG23 in "Table 5-14. Pad Configuration Ball Names" on page 1938 and "5.1.2.4.37 PADMMR_MCU_PADCONFIG23 Register ( Offset = 405Ch) [reset = 14000h]" on page 2305.
The reset value shows TX_DIS=0(enabled) and RXACTIVE=0(disabled).
Since the MCU_PORz is an input, it must be TX_DIS=1(disabled) and RXACTIVE=1(enabled), right?
How should I set MCU_PADCONFIG23?

    Hello Futoshi-san,

    Deep apologies for the delayed reply here, we had an unexpected absence of an expert and didn't catch that this question had gone unanswered last week.

    The MCU_PADCONFIG settings should be generated as part of the SysConfig outputs and so by selecting the PORz function in SysConfig that should already be handled for you as part of the default configuration for the MCU_PORz function.

    Best Regards,
