NOTES

1. DATA[15:0] are synchronized during reset only. MODCLK and ADC pins are synchronized only when used

as input port pins.

2. BERR, HALT only synchronized if late BERR or HALT.

3. EXTAL, XFC, and XTAL are clock reference connections.

4. VRH and VRL are ADC reference voltage points.

I/O

Description

O

Output-only signals that are always driven. No external pull-up required.

O

Type A output with weak P-channel pull-up during reset.

O

Three-state output that includes circuitry to pull up asserted output before high

impedance is established, to ensure rapid rise time. An external holding resistor is

required to maintain logic level while in the high-impedance state. Pins with this type of

driver may only go into high-impedance state under certain conditions. The TSC signal

can put all pins with this type of driver in high-impedance state.

O

Type B output that can be operated in an open-drain mode.
