3. Overview
The IS-Dev Kit-1 has a flash EEPROM that can hold up to 255 images and attributes. The EEPROM is
rated for 100,000 write cycle.
These images and Attributes can be downloaded to the IS-Dev Kit-1 via RS232 communication.
The IS-Dev Kit-1 has internal RAM to hold the data for an image and attributes. These data are used to
refresh the LCD display and backlighting.
Upon switch presses, timer expire or command from host the data can be read from any location of
EEPROM to internal RAM.
Host also can change the data on the internal RAM directly.
The switch activity and timer expires are reported via RS232.
Power-Up (Steps 1,2,3)
Upon power-up or reset, controller performs the following steps:
Step 1: Check if the RAM has been programmed. Compare the check string to EEPROM string.
Step 2: Write all the default initialize values to EEPROM as follows:
