L9952GXP software driver platform types
35/46
Table 41.
L9952drv_VsLockoutModeType
Type
enum
Range
L9952DRV_VS_LOCKOUT_DISABLE
Disables Vs lockout after a Vs over/under
voltage condition has disappeared. Outputs
automatically recover according to the output
settings in the CR0 register.
L9952DRV_VS_LOCKOUT_ENABLE
Enables Vs lockout. After a Vs over/under
voltage recovery, outputs remain off until the
status register 1 bits 0 and 1 are cleared by
the CLR command, using bit 21 of control
regsiter 1.
Description
Defines Vs lockout modes for controlling automatic recovery after Vs over/under
voltage recovery of the L9952GXP
Table 42.
L9952drv_RelayShutdownModeType
Type
enum
Range
L9952DRV_RELAY_SHUTDOWN_EN
ABLE
Enables shutdown of relay outputs during Vs
over/under voltage of the L9952GXP.
REL1.2 turned off in case of Vs over/under
voltage.
L9952DRV_RELAY_SHUTDOWN_DIS
ABLE
Disables shutdown of relay outputs during
Vs over/under voltage of the L9952GXP.
REL1.2 remain on in case of Vs over/under
voltage.
Description
Defines modes which control Vs over/under voltage shutdown of REL1.2 (low side drivers)
Table 43.
L9952drv_IntModeType
Type
enum
Range
L9952DRV_INT_DISABLE
Disables interrupt mode
L9952DRV_INT_ENABLE
Enables interrupt mode
Description
Defines modes which control the interrupt mode of the L9952GXP
Table 44.
L9952drv_StatusRegType
Type
uint32
Range
0..0x00FFFFFF
Description
The L9952drv_StatusRegType defines global data types for access to a complete
local copy of the L9952GXP status registers 0 and 1. Access to the internal structure
and particular bit variables of each status register is provided by a set of masks
related to each bit variable inside the status register.
