High-voltage Serial Programming
If the LSB in RDY/BSY data byte out is ‘1’, a programming operation is still pending. Wait until
this bit returns ‘0’ before the next instruction is carried out.
Within the same page, the low data byte must be loaded prior to the high data byte.
After data is loaded to the page buffer, program the EEPROM page, see
166.
This section describes how to program and verify Flash Program memory, EEPROM Data mem-
ory, Lock bits and Fuse bits in the ATtiny24/44/84.
