mDOC H3 is reset by assertion of the RSTIN# input. When this signal is negated, mDOC H3
initiates a download procedure from the flash memory into the internal Programmable Boot
Block. During this procedure, mDOC H3 does not respond to read or write access.
Host systems must therefore observe the requirements described below for initial access to
mDOC H3. Any of the following methods may be employed to guarantee first-access timing
requirements:
Hosts that use mDOC H3 to boot the system must employ the latter option or use another method
to guarantee the required timing of initial access.
