Interrupt Register 2 Status (8) (Read Only)
For all bits in this register, a “1” means the associated interrupt condition has occurred at least once
since the register was last read. A ”0” means the associated interrupt condition has NOT occurred
since the last reading of the register. Reading the register resets all bits to 0, unless the interrupt mode
is set to level and the interrupt source is still true. Status bits that are masked off in the associated
mask register will always be “0” in this register. This register defaults to 00.
The bits of this register serve as a mask for the Interrupt 1 Register. If a mask bit is set to 1, the error
is considered unmasked, meaning that its occurrence will affect the INT pin and the status register. If
a mask bit is set to 0, the error is considered masked, meaning that its occurrence will not affect the
INT pin or the status register. The bit positions align with the corresponding bits in Interrupt Register
1. This register defaults to 00.
The two Interrupt Mode registers form a 2-bit code for each Interrupt Register 1 function. This code
determines whether the INT pin is set active on the arrival of the interrupt condition, on the removal
of the interrupt condition, or on the continuing occurrence of the interrupt condition. These registers
default to 00.
00 - Rising edge active
01 - Falling edge active
10 - Level active
11 - Reserved
