4.2.30 RESBEHAVCTL Register (Offset = 0x1D8) [reset = 0x00FFFFFF]
Reset Behavior Control Register (RESBEHAVCTL)
The Reset Behavior Control Register contains system management controls.
The RESBEHAVCTL register effect occurs immediately when the register is changed. The next power-on reset sequence returns the reset value.
If any of the following bit fields are set to 0x3 when a reset occurs, a simulated POR is generated and the appropriate reset cause is set in the Reset Cause (RESC) register. During a simulated POR, registers are reloaded and the bootloader is executed. If a full POR is initiated, the POR bit in the RESC register is set and all other bits are cleared.
RESBEHAVCTL is shown in Figure 4-36 and described in Table 4-43.
