Notes

1. WK_MEAS is by default configured for standard WK functionality (Static Sense on WK). If WK_MEAS is set and

FO is not activated then the bits WK_EN and GPIO_CTRL are ignored. If FO is activated then WK_MEAS cannot

be set to ‘1’ and SPI_Fail is set. If the bit is set to ‘1’ then the measurement function is enabled during Normal

Mode & the bits WK_EN are ignored. The bits WK_LVL and GPIO_LVL bits are not updated and are reset.

2. The wake source CAN is selected in the register BUS_CTRL_0 by setting the respective bits to ‘Wake Capable’

3. Failure Handling Mechanism: When the device enters SBC Fail-Safe Mode due to a failure (TSD2, WD-

Failure,...) and WK_MEAS = ‘0’, the WK_CTRL_1 is modified by the SBC to ‘x0x0 0001’ in order to ensure that

the device can be woken again. In case WK_MEAS is ‘1’ then WK will not be available as an automatic wake

source in SBC Fail-Safe Mode.
