5.15.2.1.1 VDDA Levels

The VDDA supply has three monitors:

  • Power-on reset (POR)
  • Power-OK (POK)
  • Brownout reset (BOR)

The POR monitor is used to keep the analog circuitry in reset until the VDDA supply reaches the correct range for the analog circuitry to begin operating. The POK monitor is used to keep the digital circuitry in reset until the VDDA power supply is at an acceptable operational level. The digital reset is only released when the Power-On Reset has deasserted and the Power-OK monitor for each supply indicates that power levels are in operational ranges. The BOR monitor is used to generate a reset to the device or assert an interrupt if the VDDA supply drops below its operational range.

NOTE

VDDA BOR and VDD BOR events are a combined BOR to the system logic, such that if either BOR event occurs, the following bits are affected:

  • The BORRIS bit in the Raw Interrupt Status (RIS) register, System Control offset 0x050
  • The BORMIS bit in the Masked Interrupt Status and Clear (MISC) register, System Control offset 0x058. This bit is set only if the BORIM bit in the Interrupt Mask Control (IMC) register has been set.
  • The BOR bit in the Reset Cause (RESC) register, System Control offset 0x05C. This bit is set only if either of the BOR events have been configured to initiate a reset.

In addition, the following bits control both BOR events:

  • The BORIM bit in the Interrupt Mask Control (IMC) register, System Control offset 0x054
  • The VDDA_UBOR0 and VDD_UBOR0 bits in the Power-Temperature Cause (PWRTC) register

See the System Control chapter of the MSP432E4 SimpleLink™ Microcontrollers Technical Reference Manual for more information on how to configure these registers.

Figure 5-2 shows the relationship between VDDA, POK, POR, and a BOR event.
