General Description

MC68HC05C9A Advance Information Data Sheet, Rev. 5.1

Freescale Semiconductor

RESET pin contains an internal Schmitt trigger as part of its input to improve noise immunity. Refer to

Chapter 5 Resets for more detail.

1.5.5 TCAP

This pin controls the input capture feature for the on-chip programmable timer. The TCAP pin contains an

internal Schmitt trigger as part of its input to improve noise immunity. Refer to Chapter 8

Capture/Compare Timer for more detail.

1.5.6 TCMP

The TCMP pin provides an output for the output compare feature of the on-chip programmable timer.

Refer to Chapter 8 Capture/Compare Timer for more detail.

1.5.7 PA0–PA7

These eight I/O lines comprise port A. The state of each pin is software programmable and all port A pins

are configured as inputs during reset. Refer to Chapter 7 Input/Output Ports for more detail.

1.5.8 PB0–PB7

These eight I/O lines comprise port B. The state of each pin is software programmable and all port B pins

are configured as inputs during reset. Port B has mask option register enabled pullup devices and

interrupt capability selectable for any pin. Refer to Chapter 7 Input/Output Ports for more detail.

1.5.9 PC0–PC7

These eight I/O lines comprise port C. The state of each pin is software programmable and all port C pins

are configured as inputs during reset. PC7 has high current sink and source capability. Refer to Chapter

7 Input/Output Ports for more detail.
