Boolean __GetADCFlag( unsigned long data, unsigned char *status )
data
Setup data
status
Pointer to the buffer in which the register content indicating A/D
converter status is stored
Acquires the status flag of the specified A/D converter.
[data]
For data, set the following parameters. To acquire multiple status flags of A/D modules at the

RAPI_AD_0
A/D module 0
RAPI_AD_1
A/D module 1
• A/D end flag (ADF) is the status flag which indicate the end of A/D conversion,
and is corresponding to the bit 15 of the A/D control/status register (ADCSR).
• Configuration of ADCSR:
ADF ADIE 0 0 TRGE 0 CONADF STC CKSL[1:0] ADM[1:0] ADCS CH[2:0]
A/D end flag
Return value
