Application Program
Hardware Configuration
To accommodate the application program and the associated hardware option configuration, the
ATAM510 is equipped with 2 on-chip EEPROM memory blocks. These are written via a 6-signal
Target Programmer Interface (TPI), comprising of 2 power lines (VDD and VSS), a Program
Mode signal (PM) and 3 data lines which are multiplexed onto 3 of the ATAM510 functional pins
- BP00, BP01 and BP02 (see
and download these along with the application program into the ATAM510, the customer can be
supplied with a dedicated PC based programmer software operating under Windows 95/98 or
Windows NT and an In-Circuit Programmer unit (ICP). The ICP is connected to the PC via a
standard PC serial interface port and to the target device or application board (for in-system pro-
gramming) via the TPI flat band cable.
Table 3-19.
The state of the ATAM510 PM pin defines the MTP operational mode i.e.. PM = high (Program
Mode), PM = low (Normal operation Mode) while the 3 TPI data lines are used to serially load or
read the customer's data into or out of the ATAM510.
The Programmer software requires only the customer's binary *.hex file which is generated by
the MARC4 program compiler and also provides the primary data base for emulation. This is dis-
played on the screen as an editable hexadecimal memory map. Contents of an already
programmed device can be read back and displayed on the same hex. form provided that the
device's “Read Lock” has not been set. A “Read Lock” Protected device, if read will appear to be
full of 'F' hex.
All hardware configurations are set up within the software's intuitive user interface by selecting
the required options from the masks provided. The available configurable hardware options are
similar to those of the ATAR510 (see “Hardware Options” section). These affect primarily port
configurations, watchdog and coded reset settings. The port driver strengths, although mask
programmable in the ATAR510 are not configurable in the MTP, all output drivers being inter-
nally “hardwired” to the default “standard drive” strength.
