1.00a sv 01/15/10 First Release
|

|
|
1.01a sv 04/15/12 Removed the APIs XGpioPs_SetMode, XGpioPs_SetModePin
|
||
|
|
XGpioPs_GetMode, XGpioPs_GetModePin as they are not
|
||
|
|
relevant to Zynq device. The interrupts are disabled
|
||
|
|
for output pins on all banks during initialization.
|
||
|
|
2.1 hk 04/29/14 Use Input data register DATA_RO for read. CR# 771667.</pre><p>
