PRODUCTION DATA.
Based on the example configuration in section Detailed Design Procedure, the following register write sequence is recommended:
ADDRESS | VALUE | REGISTER NAME | COMMENTS |
---|---|---|---|
0x08 | 0x04D6 | RCOUNT0 | Reference count calculated from timing requirements (1 kSPS) and resolution requirements |
0x10 | 0x000A | SETTLECOUNT0 | Minimum settling time for chosen sensor |
0x14 | 0x1002 | CLOCK_DIVIDERS0 | FIN_DIVIDER0 = 1, FREF_DIVIDER0 = 2 |
0x19 | 0x0000 | ERROR_CONFIG | Can be changed from default to report status and error conditions |
0x1B | 0x020C | MUX_CONFIG | Enable Channel 0 in continuous mode, set Input deglitch bandwidth to 3.3MHz |
0x1E | 0x9000 | DRIVE_CURRENT0 | Sets sensor drive current on channel 0 |
0x1A | 0x1601 | CONFIG | Select active channel = ch 0, disable auto-amplitude correction and auto-calibration, enable full current drive during sensor activation, select external clock source, wake up device to start conversion. This register write must occur last because device configuration is not permitted while the LDC is in active mode. |
ADDRESS | VALUE | REGISTER NAME | COMMENTS |

0x09 | 0x04D6 | RCOUNT1 | Reference count calculated from timing requirements (1 kSPS) and resolution requirements |
0x10 | 0x000A | SETTLECOUNT0 | Minimum settling time for chosen sensor |
0x11 | 0x000A | SETTLECOUNT1 | Minimum settling time for chosen sensor |
0x14 | 0x1002 | CLOCK_DIVIDERS0 | FIN_DIVIDER0 = 1, FREF_DIVIDER0 = 2 |
0x15 | 0x1002 | CLOCK_DIVIDERS_1 | FIN_DIVIDER1 = 1, FREF_DIVIDER1 = 2 |
0x19 | 0x0000 | ERROR_CONFIG | Can be changed from default to report status and error conditions |
0x1B | 0x820C | MUX_CONFIG | Enable Ch 0 and Ch 1 (sequential mode), set Input deglitch bandwidth to 3.3MHz |
0x1E | 0x9000 | DRIVE_CURRENT0 | Sets sensor drive current on ch 0 |
0x1F | 0x9000 | DRIVE_CURRENT1 | Sets sensor drive current on ch 1 |
0x1A | 0x1601 | CONFIG | Disable auto-amplitude correction and auto-calibration, enable full current drive during sensor activation, select external clock source, wake up device to start conversion. This register write must occur last because device configuration is not permitted while the LDC is in active mode. |
