### Description

```asn1
rsuSpatStatus OBJECT-TYPE
SYNTAX BITS{manual(0), stopTime(1), failureFlash(2), preempt(3), priority(4), fixedTime(5), trafficDependent(6), standby(7), failureMode(8), invalidMAP(12), invalidSPaT(13)}
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"If a bit is enabled or active, the associated bit shall be set to (1). The definition of the term 'recent' is defined by the system in use. Bit 0 is equal to Bit 0 of the BIT STRING of DE_IntersectionStatusObject, Bit 1 is equal to Bit 1, etc.
Bit 0: Enabled when unitControlStatus is remoteManualControl (9) or localManualControl (10)
Bit 1: Enabled when Bit 4: Stop Time in unitAlarmStatus2 is TRUE
Bit 2: Enabled when unitFlashStatus is localManual (4), faultMonitor
(5), or mmu (6). This bit may also be enabled if the preemptState is other(1) and indeterminate.
Bit 3: Enabled when the preemptState for any preempt is any value other than notActive (2) or notActiveWithCall (3). This bit may also be enabled if the preemptState is other(1) and determinate.
Bit 4: Enabled when the priorityStrategyRequestStatusInCO for any priority request is a value of requestQueued (2), or activeProcessing (4).
Bit 5: Enabled if the CU is operating in fixedTime mode. This bit and bit 6 cannot both be simultaneously active (1).
Bit 6: Enabled if the CU is operating in an actuated mode. This bit and bit 5 cannot both be simultaneously active (1).
Bit 7: Enabled if the unitFlashStatus is automatic (3), startup (7), or preempt (8).
Bit 8: Controller failure or failure in operation.
Bit 9: Reserved. SET to 0.
Bit 10: Reserved. SET to 1.
Bit 11: Reserved. SET to 1.
Bit 12: Enabled if the MAP message is invalid.
Bit 13: Enabled if the SPaT message is invalid.
Bits 14-15: Reserved
The default bit value for Bits 10 and 11 is enabled (1). The default bit value for all other Bits is disabled (0).
See Section 2.5 of RFC 3416 for encoding."
