Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 15

HLVDEN: High/Low-Voltage Detect Power Enable bit

1 = HLVD is enabled

0 = HLVD is disabled

bit 14

Unimplemented: Read as ‘0’

bit 13

HLSIDL: HLVD Stop in Idle Mode bit

1 = Discontinues module operation when device enters Idle mode

0 = Continues module operation in Idle mode

bit 12-8

Unimplemented: Read as ‘0’

bit 7

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>)

bit 6

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

bit 5

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

bit 4

Unimplemented: Read as ‘0’

bit 3-0

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 the actual trip point, see Section 29.0 “Electrical Characteristics”.
