System Features
5.1.1.2
SBC Init Mode
In SBC Init Mode, the device waits for the microcontroller to finish its startup and initialization sequence. In
the SBC Init Mode any valid SPI command will bring the SBC to SBC Normal Mode. During the long open
window the watchdog has to be triggered. Thereby the watchdog will be automatically configured.
A missing watchdog trigger during the long open window will cause a watchdog failure and the device will
enter SBC Restart Mode.
Wake events are ignored during SBC Init Mode and will therefore be lost.
Note:
Any SPI command will bring the SBC to SBC Normal Mode even if it is a illegal SPI command (see
Chapter 16.2
).
Note:
For a safe start-up, it is recommended to use the first SPI command to trigger and to configure the
watchdog (see
Chapter 15.2
).
Note:
At power up no
VCC1_UV
will be issued nor will FOx be triggered as long as VCC1 is below the V
RT,x
threshold and if VS is below the VCC1 short circuit detection threshold
V
S,UV
. The RO pin will be kept
low as long as VCC1 is below the selected V
RT,x
threshold.
