Description
0 IPP
INTN pin interrupt pin mode control.
0: INTN pin is configured for open-drain mode (external pullup
to VDDIO required) (default).
1: INTN pin is configured for active drive or “push-pull” mode.
Drive level is to VDDIO.
1 IAH
Interrupt level control, sets the active drive level of the INTN pin.
0: Interrupt request is active low (default).
1: Interrupt request is active high.
2 INT_WAKE
WAKE interrupt (SNIFF to WAKE) enable
0: No interrupt is generated when SNIFF activity is detected and
the device auto-transitions to CWAKE mode (default).
1: Generate an interrupt when activity is detected in SNIFF
mode and the device auto-transitions to CWAKE mode.
3 INT_ACQ
Interrupt on sample or acquisition enable
0: No interrupt generated when new sample data is acquired
(default).
1: Generate an interrupt when new sample data is acquired
(applies to new data written to output registers or FIFO). This
enable is paired with the NEW_DATA flag in register 0x08.
4 INT_FIFO_EMPTY FIFO empty interrupt enable.
0: No interrupt is generated when the FIFO is empty or
completely drained of sample data (default).
1: Generate an interrupt when the FIFO is empty. This interrupt
is paired with the FIFO_EMPTY flag in register 0x08. Note that
this interrupt is independent of the FIFO threshold level, and will
only activate when the FIFO sample count has reached a value
of 0.
