12-Bit Incremental ADC Datasheet ADCINC12 V 5.3 (Cypress) - 19
| Manufacturer | Cypress |
| Description | The ADCINC12 User Module implements a 12-bit incremental A/D that generates a 12-bit, full-scale 2's complement output (+2047 to -2048 count range) with several input ranges to select from. Input voltage ranges, including rail-to-rail, may be measured by configuring the proper reference voltage and analog ground. It supports sample rates from 7.8 sps to 480 sps |

12-Bit Incremental ADC
ADCINC12_ClearFlag Description:
Resets the data-available flag.
C Prototype:
void ADCINC12_ClearFlag(void)
Assembly:
lcall ADCINC12_ClearFlag
Parameters:
None
Return Value:
None
Side Effect:
The A and X registers may be modified by this or future implementations of this function. The same is true for all RAM page pointer registers in the Large Memory Model (CY8C29xxx). When necessary, it is the calling function's responsibility to preserve the values across calls to fastcall16 functions. Currently, only the CUR_PP page pointer register is modified.
