Hardware Operation

When power is applied to the board, reset circuit holds the processor in
reset for approximately 30 ms. Reset is then deasserted, and the processor
begins the boot process. The
ADSP-2181processor are grounded; the processor boots from the
byte-wide memory interface which is connected to the EPROM socket. If
the EPROM supplied with the board is installed in the socket, the opera-
tion of the board is proceed as documented in the software section of this
manual.
