PRELIMINARY DATA SHEET
13. Port Interrupts
Port interrupts are the interface of the Interrupt Controller to
the external world. Six U-Port pins and alternatively six P-
Port pins are connected to the module via their special input
lines (Fig. 13–1). HW Option programmable multiplexers
define which port signal is actually connected to the Trigger
Mode Logic (Table 13–1). The P-Ports are actually analog
input ports, thus Schmitt Triggers are enabled if the P-Ports
are selected as port interrupts. The input sampling frequency
is f
SLOW modes.
Fig. 13–1:
The user can define the trigger mode for each port interrupt
by the interrupt port mode register.
The Trigger Mode defines on which edge of the interrupt
source signal the Interrupt Controller is triggered. The trig-
gering of the Interrupt Controller is shown in figure 13–2.
For the effect of CPU clock modes on the operation of this
module refer to section “CPU and Clock System” (see
Table 4–1 on page 37).
Precautions
Parallel usage of a P-Port as analog and port interrupt input
is possible but not recommended. In this case the Schmitt

Trigger input circuit is enabled. This is the reason why input
levels other than AV
rents in the Schmitt Trigger circuit and thus lead to higher
power consumption.
