Installation Instructions
3 - Installation Instructions
The MSC8101ADS may be configured according to the required working environment as follows:
• Host Controlled Operation through OnCE Port
• Host Interface Operation through HDI16 Port
• Stand-Alone Mode
3•1 OnCE Connection Scheme
In this configuration the MSC8101ADS is controlled by a host computer via the OnCE Port, which
is a subset of the JTAG port. This configuration allows for extensive debugging using on-host de-
bugger. The host is connected to the ADS by a Command Converter provided by a third party
(Macraigor Systems).

3•2 Host I/F Operation
In this configuration the MSC8101ADS is using HDI16 I/F that provide 16-bit wide, full-duplex,
double-buffered, parallel port to connect directly to the data bus of a host processor. The HDI16
supports two classes of interfaces:
• Host processor/Microcontroller (MCU) connection interface
• DMA controller interface
A Host Device may be connected to the ADS via dedicated 36pin two rows header or via 128pin
DIN - connector P2.
