[31-28] OLD_CLR port1; [27-24] OLD_CLR port0; 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). [23-16] OLD_SET [23-16] port1; OLD_SET port0; 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). [15-12] OLD_VALUE [11-8] port1; OLD_VALUE port0; RO; These bits 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). [7-4] INT_STATE port1; [3-0] INT_STATE RO port0; 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). Global register.
