3.6 Interrupt Enable Control Registers
Four registers enable interrupts to appear on the STAT_INT interrupt output pin (pin 64). The EN_LINE_INT
(0x2D), EN_EVENT_INT (0x2E), EN_OVFL_INT (0x2F), and EN_CELL_INT (0x30) enable interrupts based
on the same bit positions in the corresponding STATUS registers. For example, the EN_LINE_INT register
enables the interrupts reported in the LINE_STATUS register.
0x2D
EN_LINE_INT (Enable Line Interrupts)
The EN_LINE_INT register is located at address 0x2D and enables interrupts for the LINE_STATUS register
(0x38). Setting a bit in EN_LINE_INT enables each interrupt condition to appear on STAT_INT.
