19.4.2.1 General Reset
A general reset occurs when a VDDBU Power-on reset is detected. The internal VDDCORE reset signal is asserted when a general reset occurs. All the reset signals are released and RSTC_SR.RSTTYP reports a general reset.
The NRST_OUT line rises two cycles after the VDDCORE reset line, as ERSTL defaults at value 0x0.
The following figure shows how the general reset affects the reset signals.
