== SMC Errors ==
These errors are generated by the [[SMC|System Management Controller]].
 
=== 0001 ===
ANA_V12P0_PWRGD is driven high by the [[ANA]] (later [[HANA]]) as long as the [[Power Rails#V_12P0|V_12P0]] rail is within tolerance. If V_12P0 ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter [[Error Codes#EC_FATAL|EC_FATAL]] and the 0001 code to be displayed on the front panel.

VREG_CPU_PWRGD is driven high by the CPU power controller as long as the [[Power Rails#V_CPUCORE|V_CPUCORE]] rail is within tolerance. If V_CPUCORE ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter [[Error Codes#EC_FATAL|EC_FATAL]] and the 0002 code to be displayed on the front panel.

VREG_GPU_PWRGD is driven high by the GPU power controller as long as the [[Power Rails#V_GPUCORE|V_GPUCORE]] rail is within tolerance. If V_GPUCORE ever drops out of tolerance, the signal is de-asserted, causing the SMC to enter [[Error Codes#EC_FATAL|EC_FATAL]] and the 0003 code to be displayed on the front panel.
