STK200 Starter Kit 9-3
Port B only has six bits, PB0 - PB5, but these are connected to bits 2 to 7 on the header
to match the functionality of the other devices. This is shown in the diagram below.
9.3.4 8-Pin Socket The 8-Pin socket has five Port bits connected: PB0 - PB4. These are connected to the
header marked “Port B”, but they are not connected to the headers in the same way as
the other sockets. The connections for this socket on the Port B header are shown
below:
9.3.5 Misc. Header The last header labelled “Misc.” has connections to processor pins other than the port
pins, especially for the AT90S8515 and AT90S4414. The layout of this header is:
9.3.6 All Sockets
If external operations do not want pull-ups on the port pin, both the switches and the
LEDs can be disconnected from the processor. To isolate the LEDs, remove the jumper
set labeled “Port B”. To isolate the switches, remove the jumper set labeled “Port D”.
9.4 Using Analog
Parts
40-pin Analog parts must be used in the socket marked “A/D parts”, and 28-pin parts
must be used in the socket marked “28-Pin”. The A/D converters use the header labeled
“Analog” for the A/D inputs. This header is connected to Port A on the 40-pin A/D socket
and Port C on the 28-pin socket. The layout of this header is shown on the following
page.
