39:0
FP[39:0]EN
Frontplane Output Enable — The FP[39:0]EN bit enables the frontplane driver outputs. If LCDEN = 0, these
bits have no effect on the state of the I/O pins. It is recommended to set FP[39:0]EN bits before LCDEN is set.
0 Frontplane driver output disabled on FP[39:0].
1 Frontplane driver output enabled on FP[39:0].
