23 TFTPP (TFT/Parallel Port). Determines whether certain balls are used for TFT or PP/ACB1/FPCI. This bit is set to 1 at
power-on if the TFT_PRSNT strap (ball P29) is pulled high.

Note: 1. PMR[27] = 0 and FPCI_MON = 0
2. PMR[27] = 1 or FPCI_MON = 1
3. ACCESS.bus interface 1 is not available if PMR[23] = 1.
4. If FPCI_MON strap is enabled, the TFT_PRSNT strap should pulled low.
22 RSVD (Reserved). Must be set equal to PMR[14] (LPCSEL). The LPC_ROM strap (ball D6) determines the power-on reset
(POR) state of PMR[14] and PMR[22].
