RESET:
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. Bits [15:8] are
unimplemented and always read zero.
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.
The CPU16 does not support this function. This bit will never be set.
Reset caused by the test submodule. Used during factory test reserved operating
mode only.
Used for factory test only.
Ports A and B are available in single-chip mode only. PORTA and PORTB can be read
or written any time the MCU is not in emulator mode.
