Table 8-1, 8-2, 8-3 list the reset values for CPU and system registers, peripheral control registers, and peripheral
data registers following a reset operation. The following notation is used to represent reset values:
— A "1" or a "0" shows the reset bit value as logic one or logic zero, respectively.
— An "x" means that the bit value is undefined after a reset.
— A dash ("–") means that the bit is either not used or not mapped, but read 0 is the bit value.
