5.2.1.1

Configuration and Operation of Cyclic Sense

The correct sequence to configure the cyclic sense is shown in Figure 6. All the configurations have to be

performed before the on-time is set in the TIMERx_CTRL registers. The settings “OFF / LOW” and “OFF / HIGH”

define the voltage level of the respective HS driver before the start of the cyclic sense. The intention of this

selection is to avoid an unintentional wake due to a voltage level change at the start of the cyclic sense.

Cyclic Sense (=TimerX) will start as soon as the respective on-time has been selected independently from the

assignment of the HS and filter configuration. The selection of the respective timer (Config C/D see

Chapter 12.2.1) must therefore be done before starting the timer. The correct configuration sequence is as

follows:

•

Configure the initial level

•

Mapping of a Timer to the respective HSx outputs

•

Configuring the respective filter timing and WK pins

•

Configuring the timer period and on-time

Figure 6

Cyclic Sense: Configuration and Sequence

Note: All configurations of period and on-time can be selected. However, recommended on-times for cyclic sense

are 0.1ms, 0.3ms and 1ms. The SPI_FAIL will be set if the on-time is longer than the period.

Cyclic Sense Configuration

Assign Timer to selected HS switch

in HS_CTRL_X

Enable WKx as wake source with

configured Timer in WK_FLT_CTRL

Cyclic Sense starts / ends by

setting / clearing On-time

Timer1, Timer2

Select Timer Period and desired

On-Time in TIMERx_CTRL

WK1, WK2, WK3 with

above selected timer

Period : 10, 20, 50, 100, 200ms, 1s, 2s

On-Time: 0.1, 0.3, 1.0, 10, 20ms

Assign TIMERx_ON to OFF/Low or

OFF/High in TIMERx_CTRL

Timer1, Timer2

Select WKx pull-up / pull-down

configuration in WK_PUPD_CTRL

No pull-up/-down, pull-down or pull-up

selected, automatic switching

Changing the settings can be done on the

fly, changes become effective at the next

on-time or period
