Detailed Description

stallGuard2 value and driver error flags register (DRV_STATUS)

Status information including stallGuard2 result, driver errors, and motor current.

Bit assignments per datasheet:

Bits 9..0: SG_RESULT - StallGuard2 result or PWM on time for coil A in standstill (10 bits) Mechanical load measurement: Higher value means lower mechanical load. Value of 0 signals highest load. Temperature measurement: In standstill, shows chopper on-time for motor coil A.
Bits 11..10: Reserved, ignore these bits
Bit 12: s2vsa - Short to supply indicator phase A
Bit 13: s2vsb - Short to supply indicator phase B
Bit 14: stealth - StealthChop indicator (1: Driver operates in StealthChop mode)
Bit 15: fsactive - Full step active indicator (1: Driver has switched to fullstep)
Bits 20..16: CS_ACTUAL - Actual motor current / smart energy current (5 bits) Actual current control scaling for monitoring smart energy current scaling
Bits 23..21: Reserved, ignore these bits
Bit 24: stallguard - StallGuard2 status (1: Motor stall detected or DcStep stall)
Bit 25: ot - Overtemperature flag (1: Overtemperature limit reached, drivers disabled)
Bit 26: otpw - Overtemperature pre-warning flag (1: Pre-warning threshold exceeded)
Bit 27: s2ga - Short to ground indicator phase A
Bit 28: s2gb - Short to ground indicator phase B
Bit 29: ola - Open load indicator phase A
Bit 30: olb - Open load indicator phase B
Bit 31: stst - Standstill indicator (1: Motor standstill, occurs 2^20 clocks after last step pulse)
