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 below, (see Section 7.6.3 on page 30). The maximum number of bytes that may be written is as follows; • $10 for AT88SC0104C through AT88SC1616C (EEPROM page size of 16 bytes) • $40 for AT88SC3216C and AT88SC6416C (EEPROM page size of 64 bytes) • $80 for AT88SC12816C and 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.
