High-voltage Serial Programming
High-Voltage Serial Programming Algorithm
ATtiny24A/44A/84A
After data is loaded to the page buffer, program the EEPROM page, see
165.
This section describes how to program and verify Flash Program memory, EEPROM Data mem-
ory, Lock bits and Fuse bits in the ATtiny24A/44A/84A.
