AM2432: Pin Multiplexing and PADCONFIG Registers

Part Number: AM2432

Hi,

Can we define values in PADCONFIG during run time or is it work like soft straps. Or is it possible to change pin functionality of multiplexed pins can be changed during working. Where can I get more data on pin multiplexing of AM2432.

GPMC0_WPn and GPMC0_A22 are muxed with same pin, N16 and GPMC0_WAIT1 and GPMC0_A21 with same pin, Y18 and GPMC0_CS3 and GPMC0_A20 with same pin, R21. How can use both functionality when I used GPMC core.

Regards

    Hello Athuljith,

    It is not recommended to change the PADCONFIG registers during runtime.

    PinMux details can be found chapter 7 of the device datasheet - Terminal Configuration and Functions. Additional details related to the PADCONFIG register can be found in the Device Configuration - Control Module (CTRLMMR) chapter of the TRM.

    Due to the high signal count of GPMC and limited pin accessibility, GPMC0_WPn, GPMC0_WAIT1, or GPMC0_CS3 are not available when more then 20 address pins (GPMC0_A[20:22]) are required. Additional details can be found in the GPMC chapter of the TRM.
