ATtiny261/461/861
Serial Programming Algorithm
After RESET is set low, the Programming Enable instruction needs to be executed first before
program/erase operations can be executed.
Table 18-9.
Note:
When programming the EEPROM, an auto-erase cycle is built into the self-timed programming
operation (in the Serial mode ONLY) and there is no need to first execute the Chip Erase
instruction. The Chip Erase operation turns the content of every memory location in both the
Program and EEPROM arrays into 0xFF.
Depending on CKSEL Fuses, a valid clock must be present. The minimum low and high periods
for the serial clock (SCK) input are defined as follows:
When writing serial data to the ATtiny261/461/861, data is clocked on the rising edge of SCK.
When reading, data is clocked on the falling edge of SCK. See
timing details.
To program and verify the ATtiny261/461/861 in the Serial Programming mode, the following
sequence is recommended (see four byte instruction formats in
