__GetADCStatus
Synopsis
<Get the status of A/D converter>
Boolean __GetADCStatus(unsigned int *status)
status
Pointer to the buffer in which the register content indicating A/D converter
status is stored.
Description
Gets the status of a specified A/D converter.
The status of interrupt bit (when using the M16C or R8C) or the value of A/D end flag
(when using the H8/300H) is stored in the first low-order bit of *status. Furthermore,
the status of A/D conversion start flag is stored in the second low-order bit of *status.
When used in the M16C, the value of A/D conversion status register 0 is stored in the 8
high-order bits of *status.
[Configuration of *status]
Value of A/D conversion status
register 0 (for only the M16C; 0 for
the R8C and H8/300H)
Value of A/D conversion start flag (for only
the R8C; 0 for the M16C and H8/300H)
Return value
If A/D converter status was successfully acquired, RAPI_TRUE is returned; if failed,
RAPI_FALSE is returned.
Functionality
A/D converter
