PERR
1: Parity error is detected in trim data. Then, self-test is dis-
abled
0: Parity error is not detected in trim data
PDZ *Note
1: Pulse is detected on Z-axis at single pulse detection
0: Pulse is not detected on Z-axis at single pulse detection
INT1
1: Interrupt assigned by INTRG[1:0] bits in Control 1
Register ($18) and is detected
0: Interrupt assigned by INTRG[1:0] bits in Control 1
Register ($18) and is not detected
INT2
1: Interrupt assigned by INTRG[1:0] bits in Control 1
Register ($18) and is detected
0: Interrupt assigned by INTRG[1:0] bits in Control 1
Register ($18) and is not detected
*Note: Must define DRDY to be an output to either INT1 or
not. This is done through bit DRPD located in Register $16.
Note: This bit value is not valid at double pulse detection
