There are four possible sources of reset. LVD (Low Voltage Detector)
reset, Power-on reset (POR), and external reset on the RESET pin
share the normal reset vector. The computer operating properly (COP)
reset and the clock monitor reset each has a vector. Entry into reset is
asynchronous and does not require a clock but the MCU cannot
sequence out of reset without a system clock.
Power-On and LVD Refer to the Clocks and Reset Generator (CRG) and the Low-Voltage
