PRODUCTION DATA
ADC_CONFIG_1 is a manufacturer-specific command for configuring or reading channel selections and modes for ADC sampling as described in Section 8.3.14.8.
This command uses the PMBus? read or write byte protocol.
The details of this register are shown in Table 9-69.
| Bit | Name | Value | Description | Default | Access |
|---|---|---|---|---|---|
7 | EOC | End of conversion indication (Active Low) | Read | ||
1 | ADC is busy (Conversion in progress) | 0 | |||
0 | Conversion done | ||||
6 | CONVST | Software conversion start control (used with MODE = 01) | Read/Write | ||
1 | Start conversion | 0 | |||
0 | Do not start conversion | ||||
5:4 | MODE | ADC sampling mode | |||
11 | Continuous conversion - Single channel | 00 | |||
10 | Single channel single conversion - External pin controlled | ||||
01 | Single channel single conversion – software controlled | ||||
00 | Continuous conversion – auto sequenced | ||||
3:0 | CONV_CH_SEL | Parameter/ADC Channel selection for sampling (MODE = 01 or 10 or 11) | |||
1001-1111 | Reserved | 0000 | |||
1000 | GND (Applicable only in MODE = 01 or 10) | ||||
0111 | VIREF (Applicable only in MODE = 01 or 10) | ||||
0110 | ADDR1 (Applicable only in MODE = 01 or 10) | ||||
0101 | ADDR0 (Applicable only in MODE = 01 or 10) | ||||
0100 | VAUX | ||||
0011 | VTEMP | ||||
0010 | IIN | ||||
0001 | VOUT | ||||
0000 | VIN |
A write command to this register should be preceded by the MFR_WRITE_PROTECT command to unlock the device first to prevent accidental accidental/spurious writes.
MODE = 10 or 01 are debug-only modes and not recommended to be used during normal operation as they prevent the ADC from sampling all the necessary signals needed for the eFuse protection features.
