Bit Description

start_conversion

R_PUSH1

Starts one ADC conversion. ADC conversion time

t_adc = t_presample + 13*t_adc_clk.

adc_presample

Activation time of analog input multiplexor and S/H

before ADC conversion.

0 : t_presample = 16 us

1 : t_presample = 96 us. Useful for high impedance

signals.

5adc_slow

ADC sampling frequency.

0 : t_adc_clk = 4 us, f_adc_clk = 250 kHz (t_adc =

t_presample + 52 us)

1 : t_adc_clk = 16 us, f_adc_clk = 62.5 kHz (t_adc =

t_presample + 208 us)

4gpio_lv

0 : High voltage range of GPIO3/4/7/8 (4:1 divider active)

1 : Low voltage range of GPIO3/4/7/8 (1:1 divider, 1.8V

max)

3:0

adc_select

b0000

Selects an ADC channel

0 : BATTEMP NTC (1:1)

1 : Temperature sensor: DIE temperature [C] = adc_result

* 0.866 - 274 (1:1)

2 : CHGIN2 (4:1, 5.5Vmax)

3 : CURR1 (1:1, 1Vmax)

4 : CURR2 (1:1, 1Vmax)

5 : CURR3 (1:1, 1Vmax)

6 : VUSB1(15:1, 15V max)

7 : CHGIN1 (4:1)

8 : VIBAT (4:1)

9 : VSUP (4:1)

10 : VEBAT (4:1)

11 : GPIO3 (4:1 or 1:1)

12 : GPIO4 (4:1 or 1:1)

13 : GPIO7 (4:1 or 1:1)

14 : GPIO8 (4:1 or 1:1)

15 : NA
