This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the Atmel
Pulses are assumed to be at least 250 ns unless otherwise noted.
In this section, some pins of the Atmel ATmega48PA/88PA/168PA are referenced by signal
names describing their functionality during parallel programming, see
28-13. Pins not 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
