NOTES:

1. DATA[15:0] are synchronized during reset only. MODCLK, QSM, MCCI and ADC pins are synchronized

only when used as input port pins.

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

3. MCCI pins used only on the MC68HC16Z4/CK16Z4.

4. PAI and PCLK can be used for discrete input, but are not part of an I/O port.

5. PWMA and PWMB can be used for discrete output, but are not part of an I/O port.

Description

O Three-state capable output signals

O Type A output with weak p-channel pull-up during reset

O

Three-state output that includes circuitry to pull up output before high impedance is established,

to ensure rapid rise time

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