157 / 239 page  8.0 Health Management (HM) (Continued) Revision 1.1 157 www.national.com 8.5.4 Voltage Reading 5V Reflects current voltage of 5V monitoring. Location: 23h Type: RO 8.5.5 Voltage Reading 12V Reflects current voltage of 12V monitoring. Location: 24h Type: RO 8.5.6 Temperature Reading Zone1 Reflects current Zone1 temperature. Location: 25h Type: RO Bit 76543210 Name VOLT_DATA Reset 00000000 Bit Description 7-0 VOLT_DATA. The high byte of the voltage data measured by the associated LMxx Sensor device. The data is interpreted as a left-aligned positive value: MSBit of the LMxx Voltage Readout register maps to bit 7 of VOLT_DATA field. Bit 76543210 Name VOLT_DATA Reset 00000000 Bit Description 7-0 VOLT_DATA. The high byte of the voltage data measured by the associated LMxx Sensor device. The data is interpreted as a left-aligned positive value: MSBit of the LMxx Voltage Readout register maps to bit 7 of VOLT_DATA field. Bit 76543210 Name TEMP_DATA Reset 0 0 0 0 0000 Bit Description 7-0 TEMP_DATA. The high byte of the Temperature Zone1 data measured by the associated LMxx Sensor device. The data is converted to a left-aligned 2’s complement value. The value represented in this register is dependent on the setting of the ZONE1_RANGE bit in the Monitor Control Register (see Section 8.5.54 on page 176). If ZONE1_RANGE is 0 the LSBit of this register represents a value of 1 °C (temperature values are between -127°C (81h) and +127°C (7Fh)). If ZONE1_RANGE bit is 1 the LSBit of this register represents a value of 2 °C (temperature values are between -254°C (81h) and +254°C (7Fh)). A value of 80h represents a sensor error. Notes: 1. TEMP_DATA is obtained by translating the Temperature Readout register data from the LMxx Sensor device, according to the algorithm shown in Figure 37 on page 158. Limit checking is done only after the temperature data has been modified (if necessary). 2. The temperature data can be low-pass filtered by setting the TEMP_FILT bit in the Monitoring Control register (see Section 8.5.54 on page 176). Winbond Electronics Corp. Advanced PC Product Center |
