VS Power-On Reset

At power up of the device, the VS Power-on Reset is detected when VS > VPOR,r and the SPI bit POR is set to

indicate that all SPI registers are set to POR default settings. VCC1 is starting up and the reset output RSTN is

kept Low. It will only be released once VCC1 has crossed VRT1,r and tRD1 has elapsed.

In case VS < VPOR,f, a device internal reset is generated and the SBC is switched Off and restarts in INIT mode

with the next VS rising. This is shown in Figure 36.
