7.6.3.21 SMPL_SLY1 0x3D (61) Initial Sampling Delay

BIT

NAME

DESCRIPTION

[7]

RSVD

Reserved — always write/read as zero.

[6:4]

INIT_VOL_DLY

This value specifies the delay from changing the MUX to the first cell voltage until the channel is

sampled. This delay is applied only once per sample request, even if oversampling is used.

0 = no delay (Recommended(1))*

1 = 2 µs

2 = 5 µs

3 = 10 µs

4 = 20 µs

5 = 50 µs

6 = 100 µs

7 = 200 µs

This value is useful when all the cell voltages should return values that are nearly the same, as it

allows one settling delay and shorter channel-to-channel delays.

See the Application and Implementation section for using non-zero settings in accordance with specific

design criteria requirements.

[3]

RSVD

Reserved — always write/read as zero

[2:0]

INIT_AUX_DLY

This value specifies the delay from changing the MUX to the first auxiliary channel until the channel is

sampled. This delay is applied only once per sample request, even if oversampling is used.

0 = no delay (Recommended(1))*

1 = 2 µs

2 = 5 µs

3 = 10 µs

4 = 20 µs

5 = 50 µs

6 = 100 µs

7 = 200 µs

This value is useful when all the AUX voltages should return values that are nearly the same, as it

allows one settling delay and shorter channel-to-channel delays.

See the Application and Implementation section for using non-zero settings in accordance with specific

design criteria requirements.

7.6.3.22 Cell_CSPER 0x3E (62) Cell Voltage and Internal Temperature Sampling Interval

BIT

NAME

DESCRIPTION

[7:4]

ADC_PERIOD_VOL

This value sets the ADC sampling interval that will be used for the cell voltages.

[3:0]

ADC_PERIOD_HTEMP

This value sets the ADC sampling interval that will be used for the analog die internal temperature

channel. See Table 9 for settings.
