RSR contains a status bit for each reset source in the MCU. RSR is updated when the
MCU comes out of reset. A set bit indicates what type of reset occurred. If multiple
sources assert reset signals at the same time, more than one bit in RSR may be set.
This register can be read at any time; writes have no effect.
Reset caused by the RESET pin.
Reset caused by the power-up reset circuit.
Reset caused by the software watchdog circuit.
Reset caused by the halt monitor.
Reset caused by a RESET instruction.
Reset caused by the test submodule. Used during system test only.
Used for factory test only.
0 = When LPSTOP is executed, the CLKOUT signal is held negated to conserve
1 = When LPSTOP is executed and EXOFF
power.
driven from the SIM clock, as determined by the state of the STSIM bit.
