10.4.5 Power-Up Timing
Mobile DiskOnChip Plus is reset by assertion of the RSTIN# input. When this signal is negated,
DiskOnChip initiates a download procedure from the flash memory into the internal Programmable
Boot Block. During this procedure, Mobile DiskOnChip Plus does not respond to read or write
accesses.
Host systems must therefore observe the requirements described below for first access to Mobile
DiskOnChip Plus. Any of the following methods may be employed to guarantee first-access timing
requirements:
•
•
•
•

Use a software loop to wait at least Tp (BUSY1) before accessing the device after the reset
signal is negated.
Poll the state of the BUSY# output.
Use the BUSY# output to hold the host CPU in wait state before completing the first access.
Host systems that boot from Mobile DiskOnChip Plus must employ option c), or use another
method to guarantee the required timing for first-time access.
