When the continuous monitoring function is started, it cycles through each measurement in sequence, and it
continuously loops through the sequence approximately once every 542.336 ms (or 67.792ms – see above). Each
measured value is compared to values stored in the Limit registers. When the measured value violates (or is equal to)
the programmed limit the Hardware Monitor Block will set a corresponding status bit in the Interrupt Status Registers.
The results of the sampling and conversions can be found in the Value RAM and are available at any time.
7.18.3.4.2 Cycle Monitoring Mode
In cycle monitoring mode, the part completes all sampling and conversions, then waits to repeat the process. It
repeats the sampling and conversion process every second (1.4 sec max). The sampling and conversion of each
voltage and temperature reading is performed once every monitoring cycle. This is a power saving mode.
The cycle monitoring function is started by doing a write to the Configuration Register, setting the Start bit (Bit 0) high.
The part then performs a “round robin” sampling of the inputs, in the order shown above.
When the cycle monitoring function is started, it cycles through each measurement in sequence, and it performs a
single conversion for each voltage and temperature approximately once every second. Each measured value is
compared to values stored in the Limit registers. When the measured value violates (or is equal to) the programmed
limit the Hardware Monitor Block will set a corresponding status bit in the Interrupt Status Registers
The results of each sampling and conversion can be found in the Value RAM and are available at any time, however,
they are only updated once every 1-1.4 seconds.
7.18.3.5
The Hardware Monitor Block contains a pair of interrupt status registers. These registers are used to reflect the state
of all temperature and voltage out-of-limit/equal-limit error conditions and diode fault conditions that the Hardware
Monitor Block monitors for. When an error occurs during the conversion cycle, its corresponding bit is set in its
respective interrupt status register. The status register bits are updated continuously through each monitoring cycle.
If a measurement is within (and not equal to) limits or if there is no diode fault, the corresponding status register bit
will be cleared to ‘0’. If the measurement is equal to the limit value or out of limit or if there is a diode fault, the
corresponding status register bit will be set to ‘1’. The diode fault conditions are described in the “External
Temperature Measurement” section. Reading the status register does NOT clear its contents. These registers
default to 0x00 on HVCC POR and Initialization.
Interrupt Status Registers
7.18.3.6
The Hardware Monitor Block can be placed in a low-power mode by writing a ‘0’ to the Configuration Register (0x40).
The low power mode that is entered is either sleep mode or shutdown mode as selected using bit 0 of the Special
Function Register (4F). These modes do not reset any of the registers of the Hardware Monitor Block.
