A software controlled reset register within the FPGA will provide software controlled resets to
the FIX, BIX and PHY functions. The FPGA will also implement a last reset register to capture the
source of the last reset generated on the board.

4.12.1 Service Processor Core Reset Domain

The service processor core includes the P2020 QorIQ Integrated Processor, its memory and the
onboard resources attached to the local bus.

4.12.1.1 Service Processor

The hard reset signal HRST_L causes the P2020 QorIQ Integrated Processor to abort all current
internal and external transactions and set all registers to their default values. HRST_L may be
asserted at any time completely asynchronously. HRST_L needs to be asserted during power-
on reset. During HRST_L assertion, the configuration input signals are sampled into registers
inside the P2020 QorIQ Integrated Processor.
