28.6 Parallel Programming Parameters, Pin Mapping, and Commands
This section describes how to parallel program and verify Flash Program memory, EEPROM Data memory,
Memory Lock bits, and Fuse bits in the ATmega48A/PA/88A/PA/168A/PA/328/P. Pulses are assumed to be at
least 250 ns unless otherwise noted.
28.6.1 Signal Names
In this section, some pins of the ATmega48A/PA/88A/PA/168A/PA/328/P are referenced by signal names
describing their functionality during parallel programming, see Figure 28-1 and Table 28-13. Pins not described
in the following table are referenced by pin names.
