The HRES_N function is intended as an emergency reset and except as indicated below, should
not be used in normal system operation.
It is necessary to use an external reset circuit (see Fig. 3) to hold the HRES_N line low until the VDD
supply reaches steady state conditions. Power-One Inc. successfully tested the On-Semi voltage
detector p/n NCP303LSN27T1 although other similar devices can also be utilized. Alternatively, the
HW_RES pin can be connected to the output of a CPLD (or similar device) and controlled via the
system supervisory circuitry.

10.7.2 JTAG Interface
The ZM7300 series DPMs feature the JTAG interface that can be used for programming the DPM with
user-specific configuration settings. JTAG boundary-scan capabilities are not currently supported.
JTAG-programmable DPMs have unique 5-digit identifiers listed in Table 6.
