Bit 15 If this bit is clear, the low watermark will be set from the supplied watermark value.
H
In addition, the device will be set to notify as soon as the low watermark condition exists
(which may be immediately, depending on the sample count).
If this bit is set, the high watermark will be set from the supplied watermark value. In
addition, the device will be set to wait until the high watermark condition exists (which may
be immediately, depending on the sample count) before allowing the low watermark
condition to be signalled.

This write-only register specifies which of the bits in the STATUS register ($40) will cause a C-BUS
interrupt to be generated (IRQN pin is pulled low).
Setting a bit to '1' will cause the corresponding status bit to generate a C-BUS interrupt when the
status bit is set to '1'. Please refer to the STATUS register ($40) for an explanation of the bits.
The default state of this register after a power-up reset is for all bits, except for bit 15 (RDY), to be
cleared to '0'. Bit 15 is set to '1', so that when the device is ready to accept commands (signified
by bit 15 (RDY) of the STATUS register ($40) being set to '1'), there will also be a C-BUS interrupt.
