8.9
The bits of this register serve as a mask for the Interrupt 2 register. If a mask bit is set to 1, the error is 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 masked,
meaning that its occurrence will not affect the INT pin or the status register. The bit positions align with the corre-
sponding bits in Interrupt 2 register. This register defaults to 00h.
8.10
The two Interrupt Mode registers form a 2-bit code for each Interrupt Register 1 function. There are three ways to
set the INT pin active in accordance with the interrupt condition. In the Rising edge active mode, the INT pin be-
comes active on the arrival of the interrupt condition. In the Falling edge active mode, the INT pin becomes active
on the removal of the interrupt condition. In Level active mode, the INT interrupt pin becomes active during the in-
terrupt condition. Be aware that the active level(Actice High or Low) only depends on the INT[1:0] bits. These regis-
ters default to 00.
8.11
The bits in this register can be associated with either channel A or B of the received data. The desired channel is
selected with the CHS bit of the Channel Status Data Buffer Control Register.
