GENERAL DESCRIPTION

REV 2.0

1.5.4 IRQ / VPP
This pin has two choices of interrupt triggering sensitivity through the IRQ bit in
the Interrupt Status and Control Register (ISCR). The choices are:
1.
edge-sensitive triggering only, or
2.
both edge-sensitive and level-sensitive triggering.
In addition, the IRQ pin may be selected to trigger and interrupt on either the rising
or falling edge of the IRQ pin signal through the EDGE bit in the ISCR.
The MCU completes the current instruction before it responds to the interrupt
request.
If the option is selected to include level-sensitive triggering, the IRQ input requires
an external resistor to V
DD for “wire-OR” operation.
The IRQ pin contains an internal Schmitt trigger as part of its input to improve
noise immunity. See Section 4.
This pin is also used to supply the MC68HC705CL48 EPROM array with the pro-
gramming voltage.
NOTE
If the voltage level applied to the IRQ pin exceeds VDD it may affect the MCU’s
mode of operation.
1.5.5 PA0-PA7
These eight I/O lines comprise Port A. The state of any pin is software program-
mable and all Port A lines are congured as inputs during power-on or reset. See
Section 7 for more details on the I/O ports. PA4 to PA7 have internal pull-up resis-
tors and can generate key board interrupt.
1.5.6 PB0-PB5
These six I/O lines comprise Port B. The state of any pin is software programma-
ble and all Port B lines are congured as inputs during power-on or reset. See
Section 7 for more details on the I/O ports. All the Port B pins PB0 - PB5 can sink
10mA to drive LEDs.
1.5.7 TCMP/RDO
This pin provides an output for the output compare feature (TCMP) of the on-chip
programmable timer system and can be programed to as Raw Data Out (RDO)
from the Caller ID module. Refer to Section 8 for additional information.
