HLVDEN: High/Low-Voltage Detect Power Enable bit
1 = HLVD is enabled
0 = HLVD is disabled
Unimplemented: Read as ‘0’
HLSIDL: HLVD Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
Unimplemented: Read as ‘0’
VDIR: Voltage Change Direction Select bit
1 = Event occurs when voltage equals or exceeds trip point (HLVDL<3:0>)
0 = Event occurs when voltage equals or falls below trip point (HLVDL<3:0>)
BGVST: Band Gap Voltage Stable Flag bit
1 = Indicates that the band gap voltage is stable
0 = Indicates that the band gap voltage is unstable
IRVST: Internal Reference Voltage Stable Flag bit
1 = Indicates that the internal reference voltage is stable and the High-Voltage Detect logic generates
the interrupt flag at the specified voltage range
0 = Indicates that the internal reference voltage is unstable and the High-Voltage Detect logic will not
generate the interrupt flag at the specified voltage range, and the HLVD interrupt should not be
enabled
Unimplemented: Read as ‘0’
HLVDL<3:0>: High/Low-Voltage Detection Limit bits
1111 = External analog input is used (input comes from the HLVDIN pin)
1110 = Trip Point 1⁽¹⁾
1101 = Trip Point 2⁽¹⁾
1100 = Trip Point 3⁽¹⁾
.

.
0000 = Trip Point 15⁽¹⁾
Note 1: For actual trip point, refer to Section 29.0 “Electrical Characteristics”.
