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.
8
Must be left floating for proper operation of the PLL.
