‘-‘ means that the value of register keeps original setting.
Table 6.2.2-1 Reset Value of Registers
6.2.2.1 nRESET Reset
nRESET is triggered by pulling nRESET pin low. nRESET pin is an asynchronous reset input pin
so that it can be used to reset the system any time.
Pull nRESET pin to < 0.3* V
DD
for > 66us will reset the chip. Once entered reset state, only high
voltage (> 0.7* V
DD
) presented on nRESET pin for >66us can exit the reset state. See nRESET
reset waveform in Figure 6.2-2.
After an nRESET reset, the PINRF bit (SYS_RSTSTS[1]) will be set, indicating the previous reset
source is an nRESET reset. Writing 1 to PINRF clears the bit.
