Figure 25. Write User Zone Command Functional Description
The Write User Zone command $B0 allows writing of data into the device's currently selected user zone (the procedure
for selecting a user zone is described in Section
The maximum number of bytes that may be written is as follows;
• $10 for Atmel
• $40 for Atmel AT88SC3216C and Atmel AT88SC6416C (EEPROM page size of 64-bytes)
• $80 for Atmel AT88SC12816C and Atmel AT88SC25616C (EEPROM page size of-128 bytes)
Each data byte within a page must only be loaded once. In anti-tearing mode the maximum value for N is $08 for all
devices. A write in Anti-Tearing mode is activated with the Set User Zone with anti-tearing command (00 B4 0B zz 00);
all subsequent writes to the user zone will be in anti-tearing mode.
If the host is not allowed to write in the zone, the device will return the "Command Unauthorized" code ($69 $00) after it
has received the P3 byte.
