11.5.1 General HAL Support
Programming Notes and Examples
Issue Date: 99/04/27
Note
Note
General HAL support covers the miscellaneous functions. There is usually no more than one or two
functions devoted to any particular aspect of SED1355 operation.
int seGetId(int DevID, int * pId)
Description:
Parameters:
Return Value: ERR_OK
void seGetHalVersion(const char ** pVersion, const char ** pStatus,
const char **pStatusRevision)
Description:
Parameters:
Return Value: None
Example:
seGetId() will disable hardware suspend on x86 platforms, and will enable the host interface
(register [1Bh]) on all platforms.
This document was written for HAL version “1.04”, so any later versions should be a
superset of the functions described here.
Reads the SED1355 revision code register to determine the chip product and
revisions. The interpreted value is returned in pID.
DevID
pId
For the SED1355 the return values are currently:
ID_SED1355_REV0
ID_UNKNOWN
Other HAL libraries will return their respective controller IDs upon detection of
their controller.
ERR_UNKNOWN_DEVICE - returned when pID returns ID_UNKNOWN.
Retrieves the HAL library version. The return pointers are all to ASCII strings. A
typical return would be: *pVersion == “1.01” (HAL version 1.01),*pStatus == “B”
(The 'B' is the beta designator), *pStatusRevision == “5”. The programmer need
only create pointers of const char type to pass as parameters (see Example below).
pVersion
pStatus
pStatusRevision - pointer to string of HAL statusRevision
const char *pVersion, *pStatus, *pStatusRevision;
seGetHalVersion( &pVersion, &pStatus, &pStatusRevision);
- registered device ID
- pointer to the int to receive the controller ID.
- operation completed with no problems
(The HAL was unable to identify the display controller).
- pointer to string of HAL version code
- pointer to string of HAL status code (NULL is release)
