4.17.1 Reset Sequence
The timing of the reset sequence supports each chip reset requirements with respect to the
power supply.
4.18 Thermal Management
The MVME2502 utilizes two on-board temperature sensors: one for the board and the other for
the CPU temperature sensor. The board temperature sensor is located near the processor. The
CPU temperature sensor is located on the processor.
The MVME2502 thermal management support will interrupt the process only to show the
current board and CPU temperature. This interrupt is routed directly to one of the processor’s
IRQ4.
The table below shows the low and high threshold temperature in order for the interrupt to be
asserted.
4.19 Real-Time Clock Battery
The MVME2502 provides a through hole socket for a CR1225 48mAh lithium battery to
provide backup power for the onboard RTC when primary power is unavailable.
4.20 Debugging Support
The following information shows the details of Artesyn debugging support as applied to the
MVME2502.
