Parallel Programming Parameters, Pin Mapping, and Commands
ATmega164P/324P/644P
Signal Names
This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATmega164P/324P/644P. Pulses are
assumed to be at least 250 ns unless otherwise noted.
In this section, some pins of the ATmega164P/324P/644P are referenced by signal names
describing their functionality during parallel programming, see
ure 25-9 on page
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
