R0P7760TH001TRK User’s Manual Power Supply Controller [Supplementary description on application switch key input] (1) When multiple keys are pressed at the same time, the corresponding bits are all set to “1,” and a KEY_ONF interrupt occurs so long as it is enabled. (2) If data in the key bit pattern register changes when multiple keys are pressed at the same time, a KEY_ONF interrupt occurs so long as it is enabled. - Example This KEY_ONF interrupt occurs when the state with switches SW1 and SW2 pressed simultaneously changes to one with switches SW1 and SW3 pressed simultaneously. (3) When multiple keys are released in the state with the keys pressed and held, a KEY_OFFI interrupt occurs so long as it is enabled. (4) When multiple keys are released, the key states immediately before key release are retained in the key bit pattern register.
