GPIO Registers
25.4.1.21 GPIO_RISINGDETECT Register (offset = 148h) [reset = 0h]
GPIO_RISINGDETECT is shown in Figure 25-27 and described in Table 25-26.
The GPIO_RISINGDETECT register is used to enable/disable for each input lines the rising-edge
(transition 0 to 1) detection to be used for the interrupt request generation.
