4.6 Jumpers overview
8088A-AVR-09/07
ATmega644 board controller it can be programmed regardless of the state of the SPI
lines. If SPI communication is used between a ATtiny and the ATmega644 a way to
ensure that programming is successful, is to erase the ATmega644 first, next
program the ATtiny and finally program the ATmega644.
During development the JTAG and DebugWire debugging interfaces are used, these
are not using the SPI lines to program the devices, and there are thus no special
procedures that should be followed to ensure successful programming.
In general the ATtinyx5 and the ATtinyx61 sockets should not be populated at the
same time, as the devices in these sockets are connected to the same traces on the
BC100. If devices are placed in both of these sockets it could potentially result in
drive contention.
A number of jumpers are available on the BC100, to be able to configure it for the
desired use. Please refer to Table 4-2 for a list of jumper and use, and refer to Figure
4-2 to identify the jumper’s location.

Use and settings
Selects if the PB1 pin on ATtinyx5 is connected to the ISP/dW header or if
it is connected to the buck converters.
Use “PROG” position (left on Figure 4-2) when programming the
ATtinyx5.
Use “CHARGE” position when the ATtinyx5 should be connected to a
buck burst converter.
Select which buck converter the supply voltage is connected to use.
Two jumpers should be mounted in side by side at the label “BUCK-A”
(40V/5A), BUCK-B” (30V/2.5A) or BUCK-C” (20V/1A). “BUCK-A is the
rightmost jumper pair on Figure 4-2
Selects if the buck PWM control signal is connected or disconnected from
the BUCK-A (40V/5A). This jumper should be mounted in the disable
position while J403 or J404 is mounted in the enable position.
Selects if the buck PWM control signal is connected or disconnected from
the BUCK-B (30V/2.5A). This jumper should be mounted in the disable
position while J402 or J404 is mounted in the enable position.
Selects if the buck PWM control signal is connected or disconnected from
the BUCK-C (20V/1A). This jumper should be mounted in the disable
position while J402 or J403 is mounted in the enable position.
Selects the resistor divider network setting for the ADC input from the
V_BAT+ voltage (positive ADC input from shunt resistor).
The divider can be set to 1/2, 1/4, 1/8, 1/12, and 1/16 V_BAT+.
Note that the setting used should match the setting on J406.
Selects the resistor divider network setting for the ADC input from the
V_BAT- voltage (negative ADC input from shunt resistor).
The divider can be set to 1/2, 1/4, 1/8, 1/12, and 1/16 V_BAT-.
Note that the setting used should match the setting on J405.
