1. The combination of PMR[21] = 1 and PMR[2] = 0 is undefined and should not be used.
2. The combination of PMR[9] = 1 and PMR[4] = 0 is undefined and should not be used.
3. 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.
