6. Resets
6.5.3
OSDR Bit (Oscillation Stop Detect Reset Detect Flag)
When an oscillator stop detect reset is generated, the MCU is reset and then stopped. This state is
canceled by hardware reset or voltage monitor 0 reset.
Note that the OSDR bit in the RSTFR register is not affected by a hardware reset, but becomes 0 (not
detected) from a voltage monitor 0 reset.
6.5.4
Hardware Reset when VCC1 < Vdet0
When a hardware reset is executed while VCC1 < Vdet0, the voltage monitor 0 reset is not performed
after the hardware reset even if the LVDAS bit in the OFS1 address is 0 (voltage monitor 0 reset
enabled after hardware reset).
