1.6.2.1 Effects of Reset
When a reset occurs, MCU registers and control bits are changed to known start-up states. Refer to the
respective module block description chapters for register reset states.
Refer to the PIM block description chapter for reset configurations of all peripheral module ports.
Refer to Table 1-5 for locations of the memories depending on the operating mode after reset.
The RAM array is not automatically initialized out of reset.
