MC3635 3-Axis Accelerometer EV3635B Quick Start Guide and Demo

mCube Proprietary. APS-045-0018v1.2 14 / 20

threshold for each axis, and an optional “false detection count” which requires multiple

sniff detection events to occur before a wakeup condition is declared.

Configure sniff and/or mode with:

MC36XX_acc.SetSniffAndOrN(MC36XX_ANDORN_OR);

The SNIFF block supports the logical AND or OR of the X/Y/Z SNIFF wakeup flags when

generating a SNIFF wakeup interrupt.

Configure sniff delta mode with:

MC36XX_acc.SetSniffDeltaMode(MC36XX_DELTA_MODE_C2P);

C2P mode: The current sample and the immediate previous sample are subtracted

generate a delta

C2B mode: The current sample and the first sample captured when entering SNIFF

mode are subtracted to generate a delta.

4.12 CONFIG INTERRUPT MODE

Configure the interrupt mode with:

MC36XX_acc.SetINTCtrl(0,0,0,0,1);

MC36XX have 5 interrupt modes – FIFO_THR | FIFO FULL | FIFO EMPTY | ACQ | WAKE.

These modes can only be enabled separately.

4.13 READ RAW COUNT DATA

Read the raw count data and SI unit measurement with:

MC36XX_acc.readRawAccel();
