D a t a
ATmega48A/48PA/88A/88PA/168A/168PA/328/328P. Pulses are assumed to be at least 250 ns
unless otherwise noted.
In this section, some pins of the ATmega48A/48PA/88A/88PA/168A/168PA/328/328P are refer-
enced by signal names describing their functionality during parallel programming, see
1
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
