The LDC1312/LDC1314 can monitor and report on conversion results and the status of attached sensors using the registers listed in Table 43.
|CHANNEL(1)||REGISTER||FIELDS [ BIT(S) ]||VALUES|
|All||STATUS, addr 0x18||12 fields are available that contain various status bits [ 15:0 ]||Refer to Register Maps section for a description of the individual status bits.|
|All||ERROR_CONFIG, addr 0x19||12 fields are available that are used to configure error reporting [ 15:0 ]||Refer to Register Maps section for a description of the individual error configuration bits.|
See the STATUS (Table 21) and ERROR_CONFIG (Table 22) register descriptions in the Register Map section. These registers can be configured to trigger an interrupt on the INTB pin for certain events. The following conditions must be met:
When a bit field in the STATUS register is set, the entire STATUS register content is held until read or until the DATAx register is read. Reading also de-asserts INTB. After first starting conversions in active mode, the first read of STATUS should performed be after assertion of INTB.
Interrupts are cleared by one of the following events:
Setting register CONFIG.INTB_DIS to b1 disables the INTB function and holds the INTB pin high.
The TI Application Note LDC1312, LDC1314, LDC1612, LDC1614 Sensor Status Monitoring provides detailed information on sensor status reporting.
