ENE KB1200 GPIO(General purpose IO) Port node
|
||
|
|
|
||
|
|
The GPIO controller provides group control of GPIO functions. Each port
|
||
|
|
group contains 32 pins. GPIO_00~GPIO_1F belong to the Port0 group,
|
||
|
|
GPIO_20~GPIO_3F belong to the Port1 group, and so on.
|
||
|
|
|
||
|
|
In particular, the 32 pins of the port group do not share the same IRQ
|
||
|
|
interrupt, but are assigned to two different IRQ interrupts in groups of 16
|
||
|
|
pins. This means that single port group provide two interrupt source.
|
||
|
|
ex.Port0 group GPIO_00~GPIO_0F shares IRQ18, and Port0 group
|
||
|
|
GPIO_10~GPIO_1F shares IRQ19.
