SUPPLYn_TH_LOWER (PMC_SYSMON_CSR) Register Bit-Field Summary
| Field Name | Bits | Type | Reset Value | Description |
|---|---|---|---|---|
| Reserved | 31:19 | razRead as zero | 0x0 | |
| val_ro | 18:16 | roRead-only | 0x0 | Power supply threshold format: 00x: Supply, exponent = -15 01x: Unipolar mode, expondent = -16 10x: Bipolar mode, exponent = -16 11x: Supply extened mode, exponent = -14 xx1: Signed xx0: Unsigned Note: This is a read-only bit field. |
| val | 15:0 | rwNormal read/write | 0x0 | When a SUPPLYn meaurement is less than the [val] bit field and the alarm is enabled by a bit in the ALARM_REGx (0 to 4) register, then: * The associated bit in the ALARM_FLAGx (0 to 4) register will be set = 1 * The output port alarm [n/32] will be set = 1 * The ISR.ALARM [n/32] will be set * An interrupt may be generated. Note: Additionally a PMBus undervoltage fault will be indicated and an SMBALERT may be generated. Format: Modified floating point when concatenated {val_ro, val}, signed or unsigned. |
