37019 #define MISCS_REG_GPIO21_INT 0x0095dcUL //Access:RW DataWidth:0x4 // GPIO INT. [3] OLD_CLR; Writing a '1' to these bit clears the corresponding bit in the OLD_VALUE register. This will acknowledge an interrupt on the falling edge of corresponding GPIO input (reset value 0). [2] OLD_SET; Writing a '1' to these bit sets the corresponding bit in the OLD_VALUE register. This will acknowledge an interrupt on the rising edge of corresponding GPIO input (reset value 0). [1] OLD_VALUE; RO; This bit indicate the old value of the GPIO input value. When the INT_STATE bit is set; this bit indicates the OLD value of the pin such that if INT_STATE is set and this bit is '0'; then the interrupt is due to a low to high edge. If INT_STATE is set and this bit is '1'; then the interrupt is due to a high to low edge (reset value 0). [0] INT_STATE; These bits indicate the current GPIO interrupt state for each GPIO pin. This bit is cleared when the appropriate OLD_SET or OLD_CLR command bit is written. This bit is set when the GPIO input does not match the current value in OLD_VALUE (reset value 0).
