NOTES
1. DATA[15:0] are synchronized during reset only. MODCLK, MCCI and ADC pins are
synchronized only when used as input port pins.
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.
4. PWMA and PWMB can be used for discrete output, but are not part of an I/O port.
5. V
RH
and V
RL
are ADC reference voltage inputs.
1. 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.

Description
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 insure rapid rise time. An external holding resistor is required to
maintain logic level while in the high-impedance state.
Type B output that can be operated in an open-drain mode.
