MC68332 MOTOROLA
MC68332TS/D 11
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.

Table 4 MCU Driver Types
Type I/O Description
A O Output-only signals that are always driven; no external pull-up required
Aw O Type A output with weak P-channel pull-up during reset
B O Three-state output that includes circuitry to pull up output before high impedance is
established, to ensure rapid rise time. An external holding resistor is required to maintain
logic level while the pin is in the high-impedance state.
Bo O Type B output that can be operated in an open-drain mode
