ATmega16HVB/32HVB
Signal names
In this section, some pins of the Atmel ATmega16HVB/32HVB are referenced by signal names
describing their functionality during parallel programming, see
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
programming characteristics.
