Serial Programming
Algorithm
2573G–AVR–07/09
When writing serial data to the ATmega165, data is clocked on the rising edge of SCK.
When reading data from the ATmega165, data is clocked on the falling edge of SCK.
See Figure 121 for timing details.
To program and verify the ATmega165 in the serial programming mode, the following
sequence is recommended (See four byte instruction formats in Table 114):
1. Power-up sequence:
2. Wait for at least 20 ms and enable serial programming by sending the Program-

issuing the third byte of the Programming Enable instruction. Whether the echo
is correct or not, all four bytes of the instruction must be transmitted. If the 0x53
did not echo back, give RESET a positive pulse and issue a new Programming
Enable command.

the 6 LSB of the address and data together with the Load Program Memory

be loaded before data high byte is applied for a given address. The Program
