Note:

There is a diode in series to the switch S_MEAS (not shown in the Figure 46), which influences the

temperature behavior of the switch. See also Figure 13.

WK_EN, GPIO configured as

Wake-up via WK/VSENSE and GPIO

WK possible

Setting the wake enable bits is

ignored, i.e. the measurement

function has priority but the bits can

be set.

If only WK_EN and/or GPIO as WK are

set while trying to go to SBC Sleep

Mode, then the SPI_FAIL flag is set

and the SBC changes into SBC Restart

Mode

SBC Fail-Safe Mode behavior WK/VSENSE is automatically

activated as wake source;

see Table 22 for GPIO behavior

Measurement function configuration

is kept, switch S_MEAS is open

WK_PUPD_CTRL

normal configuration is possible

no pull-up or pull-down enabled

FO functionality

FO functionality is available if

configured accordingly

FO functionality is not available.

FO/GPIO must be set to Off before

setting WK_MEAS. Otherwise the

SPI_FAIL flag is set.

Differences between Normal WK Function and Measurement Function (cont’d)

Affected Settings/Modules

for WK/VSENSE and

FO/GPIO Inputs

WK_MEAS = 0

WK_MEAS = 1
