3.3. System Configuration

Standalone System

When the standalone system is configured, a user application program should be stored in the built-in Flash memory (TC35680) or

an external EEPROM (TC35681) in the User-App mode.

In the User-App mode, a boot loader in the mask ROM reads the user application program from the built-in Flash memory or an

external EEPROM and writes to the RAM in the standalone system, then the user application program is executed. An external CPU

is not necessary in the system. Then, the standalone operation is enabled.

Host-Controlled System

The host-controlled system can be configured by the following three methods;



Using the HCI mode.



Using the Complete mode.



Using the User-App mode.

The built-in firmware is used to configure the system in the HCI and the Complete modes.

In the User-App mode, a user application program is executed by the CPU in TC35680/TC35681. And in the system, the host can

operate together with it.
