Software for EV kits using the Maxim 80C32 module is
divided into three elements: the interface program run-
ning on an IBM-compatible PC, a module program
located in EPROM, and a program supplied on disk
that is transferred to the RAM located on the module.
The EPROM resident program initializes the 80C32,
establishes communications over the RS-232 link, ver-
ifies the static RAM, and downloads other programs.
Its operation starts on power-up and whenever the
reset button is pressed. After reset, the program waits
indefinitely to receive a character over the RS-232
port. When the first character is received, a logon
banner identifying the module and firmware revision is
transmitted.

EPROM Resident Program
Software Architecture
Immediately following transmission of the logon banner,
the program runs a checker routine for the on-board
256kbit static RAM. The RAM is filled with several pat-
terns and then read to verify that each pattern has been
retained. A pass or fail indication is displayed on the
personal computer after each pass. EV kit software
requires proper operation of the RAM. Do not attempt
to use the board if any of the RAM checks fail.
Two other programs for the EV kits are provided on a
floppy disk shipped with each kit. One program acts as
the user interface and transmits commands to the
80C32 module. The other is an 80C32 application pro-
gram that executes from the RAM located on the mod-
ule. The procedure for loading the programs varies with
each kit, so follow the instructions provided.
