1. DATA[15:0] are synchronized during reset only. MODCLK is synchronized only when used as an input port
2. EXTAL, XFC, and XTAL are clock reference connections.
3. PAI and PCLK can be used for discrete input, but are not part of an I/O port.

Output-only signals that are always driven; no external pull-up required
Type A output with weak P-channel pull-up during reset
Three-state output that includes circuitry to pull up output before high impedance is es-
tablished, to ensure rapid rise time. An external holding resistor is required to
maintain logic level while the pin is in the high-impedance state.
Type B output that can be operated in an open-drain mode
