VRT_T1 - RW – 8 bits - [PM_Reg: 3Eh]

Field Name

Bits

Default

Description

VRT_T1

7:0

01h

The RTC battery is sampled (to conserve power) periodically
to checks its state of health. VRT_T1 and VRT_T2 make up
the interval of the checking. When VRT_Enable is high, the
battery is being sampled. When VRT_enable is low, the
battery is not being sampled. This register defines the time
of VRT enable being high for RTC battery monitor circuit, in
miliseconds.

VRT_T1 register.

VRT_T2 - RW – 8 bits - [PM_Reg: 3Fh]

Field Name

Bits

Default

Description

VRT_T2

7:0

FFh

This register defines the time of VRT enable being low for the
RTC battery monitor circuit, in 4 ms increment.

VRT_T2 register.

Field Name

Bits

Default

Description

AD_Pull_UpB

7:0

00h

This register controls integrated pull-up for AD[31:24]
respectively.
0: Enable
1: Disable
