Table 26-6.
This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATmega16A. Pulses are assumed to be at
least 250 ns unless otherwise noted.
In this section, some pins of the ATmega16A are referenced by signal names describing their
functionality during parallel programming, see
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
