Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

CMVREN: Comparator Voltage Reference Enable bit(1, 2)

1 = CVREF circuit powered on and routed to CVREF input of the Comparator

0 = 0.6 Volt constant reference routed to CVREF input of the Comparator

Unimplemented: Read as ‘0’

VRR: CVREF Range Selection bit

1 = Low range

0 = High range

FVREN: 0.6V Reference Enable bit(2)

1 = Enabled

0 = Disabled

VR<3:0>: Comparator Voltage Reference CVREF Value Selection bits (0  VR<3:0>  15)

When VRR = 1: CVREF = (VR<3:0>/24) * VDD

When VRR = 0: CVREF = VDD/4 + (VR<3:0>/32) * VDD

Note 1: When CMVREN is low, the CVREF circuit is powered down and does not contribute to IDD current.

2: When CMVREN is low and the FVREN bit is low, the CVREF signal should provide Vss to the comparator.
