NOTES:

1 Refers to pin’s primary function.

2 Pull-up enabled internally on this signal for this mode.

3 The SDRAM functions of these signals are not programmable by the user. They are dynamically switched by the processor when

accessing SDRAM memory space and are included here for completeness.

4 Primary functionality selected by asserting the DRAMSEL signal (SDR mode). Alternate functionality selected by negating the

DRAMSEL signal (DDR mode). The GPIO module is not responsible for assigning these pins.

5 GPIO functionality is determined by the edge port module. The GPIO module is only responsible for assigning the alternate functions.

6 If JTAG_EN is asserted, these pins default to Alternate 1 (JTAG) functionality. The GPIO module is not responsible for assigning

these pins.

7 Pull-down enabled internally on this signal for this mode.
