8.4.6 Restart Mode

Restart mode is a transitional mode. This mode can be entered from any of the other modes depending upon whether fail-safe mode is disabled. In this mode, the LDO is ramping when coming from sleep mode or fail-safe mode where the LDO was turned off, like a TSD event. Once VCC ≥ UVCC for tRSTN_act (~2 ms), the device enters standby mode. While in restart mode, the nRST pin is latched low. Each time restart mode is entered the restart mode counter is incremented.

Note:

The SWE timer starts when the device enters restart mode. If the SWE timer times out, the device enters fail-safe mode. If fail-safe mode is disabled, the device enters sleep mode.

Figure 8-38 Restart Mode Pin Control
Figure 8-39 Restart Mode SPI Control
Note:

  • A watchdog failure, soft reset or nRST event resets tNRST_TOG to default value of typically 2 ms

  • The typical time between the release of a nRST input pulse for device to enter restart mode is ~ 200 ns
