Electrical Characteristics
If the PORESET or HRESET signal is not asserted before this condition, there is a possibility of disturbing
the programmed state of the flash. In addition, the state of the pads are indeterminant until PORESET or
HRESET propagates through the device to initialize all circuitry.
F.9.2
PORESET or HRESET must be asserted during power-down prior to any supply dropping out of specified
operating conditions.
An additional constraint is placed on PORESET assertion since it is an asynchronous input. To assure that
the assertion of PORESET does not potentially cause stores to keep-alive RAM to be corrupted (store
single or store multiple) or non-coherent (store multiple), either of the following solutions is
recommended:
The amount of delay that should be added to PORESET assertion is dependent upon the frequency of
operation and the maximum number of store multiples executed that are required to be coherent. If store
multiples of more than 28 registers are needed and if the frequency of operation is lower that 56 MHz, the
delay added to PORESET assertion will need to be greater than 0.5 µs. In addition, if KAPWR features
are being used, PORESET should not be driven low while the V

Assert HRESET at least 0.5 µs prior to when PORESET is asserted.
Assert IRQ0 (non-maskable interrupt) at least 0.5 µs prior to when PORESET is asserted. The
service routine for IRQ0 should not perform any writes to keep-alive RAM.
