reading INT1_SRC itself. Default value: 0.
(0: interrupt request not latched; 1: interrupt request latched)
D4D_INT1
4D enable: 4D detection is enabled on INT1 pin when 6D bit on INT1_CFG is set to
1.
LIR_INT2
Latch interrupt request on INT2_SRC register, with INT2_SRC register cleared by
reading INT2_SRC itself. Default value: 0.
(0: interrupt request not latched; 1: interrupt request latched)
D4D_INT2
4D enable: 4D detection is enabled on INT2 pin when 6D bit on INT2_CFG is set to
1.
