USER’S MANUAL
NOTES:
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.
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.
