CLOCK CIRCUIT:
JUMPER DESCRIPTION:
Quartz crystal 32 768 Hz is connected to MSP430F2618 pin 8 (XIN) and pin 9
(XOUT/TCLK).
There is an option for a high speed crystal oscillator to be connected to the
MSP430F2618 pin 52 (XT2OUT) and pin 53 (XT2IN).
P_IN
P_OUT
When this jumper is closed, the board is power supplied by the
standard JTAG pin 2. This is only possible when the consumption of
the board is not very high which is typically the case with MSP430
microcontrollers. If this jumper is open the board should be power
supplied by another external source. This jumper and P_OUT should
always be reversely open/closed, i.e. if P_IN is closed, P_OUT should
be open and vice versa.
Default state is closed.
When this jumper is closed, the board is power supplied not by the
JTAG but from external source. Then the JTAG has to synchronize
with the working voltages which is done through this line. This is
especially important when debugging with JTAG. This jumper and
P_IN should always be reversely open/closed, i.e. if P_OUT is closed,
P_IN should be open and vice versa.
Default state is open.
