gpio_swporta_ddr
This register establishes the direction of each corresponding GPIO Data Field Bit.
Check the GPIO chapter in the handbook for details on how GPIO2 is implemented.
| Module Instance | Base Address | Register Address |
|---|---|---|
| gpio0 | 0xFF708000 | 0xFF708004 |
| gpio1 | 0xFF709000 | 0xFF709004 |
| gpio2 | 0xFF70A000 | 0xFF70A004 |
Offset: 0x4
Access: RW
Important: To prevent indeterminate
system behavior, reserved areas of memory must not be accessed by software or
hardware. Any area of the memory map that is not explicitly defined as a register
space or accessible memory is considered reserved.
