CY7C67300
Interrupt 0 Polarity Select (Bit 1) | Reserved |
The Interrupt 0 Polarity Select bit selects the polarity for IRQ0. | Write all reserved bits with ’0’. |
1: Sets IRQ0 to rising edge |
|
0: Sets IRQ0 to falling edge |
|
Interrupt 0 Enable (Bit 0) |
|
The Interrupt 0 Enable bit enables or disables IRQ0. The GPIO |
|
bit on the interrupt Enable register must also be set in order for |
|
this for this interrupt to be enabled. |
|
1: Enable IRQ0 |
|
0: Disable IRQ0 |

The GPIO n Output Data register controls the output data of the GPIO pins. The GPIO 0 Output Data register controls GPIO15 to GPIO0 while the GPIO 1 Output Data register controls GPIO31 to GPIO16. When read, this register reads back the last data written, not the data on pins configured as inputs (see Input Data Register).
