JP6 - LCDPWR Polarity
LCDPWR output from S1D13705 is only active high but some panels may require an active
low signal. To provide both active high and active low signals, the output from S1D13705
is inverted and the selection is made by the setting of JP6
When the jumper is in position 1-2, LCDPWR signal to the panel is active low
When the jumper is in position 2-3, LCDPWR signal to the panel is active high

JP7 - CLKI Selection
JP7 selects the source for CLKI input on S1D13705.
When the jumper is in position 1-2, CLKI signal is provided by external oscillator U2
When the jumper is in position 2-3, CLKI signal is the same as BCLK signal
