PMR[23] = 0 and

FP_VDD_ON

PMR[23] = 1

The combination of PMR[21] = 1 and PMR[2] = 0 is undefined and should not be used.

The combination of PMR[9] = 1 and PMR[4] = 0 is undefined and should not be used.

These TFT outputs are reset to 0 by POR# if the TFT_PRSNT strap is pulled high or PMR[10] = 0. This relates to signals TFTD[17:0],

TFTDE, TFTDCK.
