Synopsis

int sub_edge_config( sub_handle hndl, int set, int* get )

Configure EDGE module.

Parameters

•set - set will be used only if get == 0. EDGE lines EDG7..EDG0 are configured by two bits Ex1,Ex0 in set where x is 7..0. set bits have following interpretation:

MSB

31..16	15	14	13	12	11	10	09	08	07	06	05	04	03	02	01	00
-	EDG7		EDG6		EDG5		EDG4		EDG3		EDG2		EDG1		EDG0
-	E71	E70	E61	E60	E51	E50	E41	E40	E31	E30	E21	E20	E11	E10	E01	E00

Ex1	Ex0	Edge Detection
0	0	No
0	1	Any change
1	0	Falling edge
1	1	Rising edge

•*get - Pointer to store current edge configuration read from SUB-20. If get is not zero function will read edge configuration otherwise it will set edge configuration

Return value

On success function returns 0. Otherwise error code.

Example

rc = sub_edge_config( hndl, 0, &edge_config ); /* Read Edge configuration */

/* EDG0 = 01B - Any change */

/* EDG1 = 01B - Any change */

/* EDG2 - 11B - Risinge edge */

/* EDG7..EDG3 not detected */

rc = sub_edge_config( hndl, 0x0035, 0 ); /* set = 0011.0101B */
