Using the Voltage and Current Peak-
Detection Registers
The voltage and current minimum- and maximum-value
records in register locations 0x08 through 0x17 can be
reset by writing a 1 to the appropriate location in register
peak_log_rst (see Table 35). The minimum-value regis-
ters are reset to 0xFF, and the maximum-value registers
are reset to 0x000.
As long as a bit in peak_log_rst is 1, the corresponding
peak-detection registers are disabled and are cleared
to their power-up reset values. The voltage and current
minimum- and maximum-detection register contents can
be held by setting bits in register peak_log_hold (see
Table 36). Writing a 1 to a location in peak_log_hold
locks the register contents for the corresponding signal
and stops the min/max detection and logging; writing a
0 enables the detection and logging. Note that the peak-
detection registers cannot be cleared while they are held
by register peak_log_hold.
The combination of these two control registers allows the
user to monitor voltage and current peak-to-peak values
during a particular time period.
