Defines

KEYSCAN_INT_THRESHOLD ((uint16_t)(0x1 << 4))

KeyScan FIFO threshold interrupt. when data in the FIFO reaches the threshold level, the interrupt is triggered.

KEYSCAN_INT_OVER_READ ((uint16_t)(0x1 << 3))

KeyScan FIFO over read interrupt. When there is no data in the FIFO, reading the FIFO will trigger this interrupt to prevent over-reading.

KEYSCAN_INT_SCAN_END ((uint16_t)(0x1 << 2))

KeyScan finish interrupt. Whether the key value is scanned or not, the interrupt will be triggered as long as the scanning action is completed.

KEYSCAN_INT_FIFO_NOT_EMPTY ((uint16_t)(0x1 << 1))

KeyScan FIFO not empty interrupt. If there is data in the FIFO, the interrupt will be triggered.

KEYSCAN_INT_ALL_RELEASE ((uint16_t)(0x1 << 0))

KeyScan all release interrupt. When the release time count reaches the set value, if no key is pressed, the interrupt is triggered.

IS_KEYSCAN_CONFIG_IT(IT) ((((IT) & (uint32_t)0xFFF8) == 0x00) && ((IT) != 0x00))

Check whether is the KeyScan interrupt.
