USER’S MANUAL
15
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; a write has no effect.
Reset caused by an external signal.
Reset caused by the power-up reset circuit.
Reset caused by the software watchdog circuit.
Reset caused by the halt monitor.
Reset caused by loss of clock frequency reference.
Reset caused by a RESET instruction.
Reset caused by the test submodule. Used during system test only.
Register is used for factory test only.
0 = Loss of reference causes the MCU to operate in limp mode.
1 = Loss of reference causes system reset.
0 = SIM clock driven by an external source and VCO off during low-power stop.
1 = SIM clock driven by VCO during low-power stop.
0 = CLKOUT held low during low-power stop.
1 = CLKOUT driven from SIM clock during low-power stop.
