1. DATA[15:0] are synchronized during reset only. MODCLK is synchronized only when used as an input port pin.

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.

3.4 Signal Descriptions

The following tables define MCU signals. Table 3-4 shows signal origin, type, and ac-

tive state. Table 3-5 describes signal functions. Both tables are sorted alphabetically

by mnemonic. MCU pins often have multiple functions. More than one description can

apply to a pin.
