This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATmega48/88/168. Pulses are assumed
to be at least 250 ns unless otherwise noted.
In this section, some pins of the ATmega48/88/168 are referenced by signal names describing
their functionality during parallel programming, see
described in the following table are referenced by pin names.
The XA1/XA0 pins determine the action executed when the XTAL1 pin is given a positive pulse.
The bit coding is shown in
When pulsing WR or OE, the command loaded determines the action executed. The different
Commands are shown in
