Figure 25-7. Serial Programming and Verify
Notes:
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:
Low: > 2 CPU clock cycles for f
High: > 2 CPU clock cycles for f

The Flash parameters are given in
Table 25-12 on page
When writing serial data to the AT90CAN32/64/128, data is clocked on the rising edge of SCK.
When reading data from the AT90CAN32/64/128, data is clocked on the falling edge of SCK.
To program and verify the AT90CAN32/64/128 in the serial programming mode, the following
sequence is recommended (See four byte instruction formats in
MISO (PDO)
MOSI (PDI)
