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 FF h This register defines the time of VRT enable being low for the
RTC battery monitor circuit, in 4 ms increment.
VRT_T2 register.
AD_Pull_UpB - RW – 8 bits - [PM_Reg: 40h]
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
AD_Pull_UpB register.
