LCD Frame Sync Routing Switch (SW4)
Frame synchronization signals FSYNC1_LCD and FSYNC2_LCD get configured
through the SW4 DIP switch settings, as illustrated in Figure 2-1 on
page 2-2.
The FSYNC1_LCD signal can be set by the PF2 programmable flag,
PPI0_SYNC1, or PPI1_SYNC1 signal. The FSYNC2_LCD signal can be set by the
PF3 programmable flag, PPI0_SYNC2, or PPI1_SYNC2 signal. Figure 2-8 and
Figure 2-9 depict the available options.

If the PF2 or PF3 programmable flag is used, ensure the flag is not
used for other purposes on the EZ-KIT Lite board (the mother
board).
