148 / 196 page  148 7598H–AVR–07/09 ATtiny25/45/85 Note: a = address high bits, b = address low bits, d = data in high bits, e = data in low bits, p = data out high bits, q = data out low bits, x = don’t care, 1 = Lock Bit1, 2 = Lock Bit2, 3 = CKSEL0 Fuse, 4 = CKSEL1 Fuse, 5 = SUT0 Fuse, 6 = SUT1 Fuse, 7 = CKDIV8, Fuse, 8 = WDTON Fuse, 9 = EESAVE Fuse, A = SPIEN Fuse, B = RSTDISBL Fuse, C = BODLEVEL0 Fuse, D= BODLEVEL1 Fuse, E = MONEN Fuse, F = SPMEN Fuse Notes: 1. For page sizes less than 256 words, parts of the address (bbbb_bbbb) will be parts of the page address. 2. For page sizes less than 256 bytes, parts of the address (bbbb_bbbb) will be parts of the page address. 3. The EEPROM is written page-wise. But only the bytes that are loaded into the page are actually written to the EEPROM. Page-wise EEPROM access is more efficient when multiple bytes are to be written to the same page. Note that auto-erase of EEPROM is not available in High-voltage Serial Programming, only in SPI Programming.
