Reset
The nRF9E5 can be reset either by the on-chip power-on reset circuitry or by the on-
chip watchdog counter.
16.7.1
Power-on Reset
The power-on reset circuitry keeps the chip in power-on-reset state until the supply
voltage reaches VDDmin (a voltage, less than 1.9V sufficiently high for digital
operation). At this point the internal voltage generators and oscillators start up, the SFRs
are initialized to their reset values, as listed in Table 62, and thereafter the CPU begins
program execution at the standard reset vector address 0x0000. The startup time from
power-on reset is normally determined by both the crystal oscillator startup time and the
frequency of the low power oscillator (LP_OSC). This total may vary from 1 to 3 ms
depending on processing, temperature and supply voltage.
