Input mode-change pin. When MODE = GND, the device is in GS mode. When MODE =
V_CC, the device is in DC mode.
O Error output. XERR is an open-drain terminal. XERR goes L when LOD or TEF is detected.
Level triggered latch signal. When XLAT = high, the TLC5945 writes data from the input shift
I register to either GS register (MODE = low) or DC register (MODE = high). When XLAT=low,
the data in the GS or DC registers is held constant and does not change.
