• Description: 8 - Bit Cmos Microcontroller
• Manufacturer: Infineon Technologies Corporation

The register TRPCTR controls the trap functionality. It contains independent enable bits
for each output signal and control bits to select the behavior in case of a trap condition.
The trap condition is a low level on the CTRAP input pin, which is monitored (inverted
level) by bit TRPF (in register IS). While TRPF=’1’ (trap input active), the trap state bit
TRPS (in register IS) is set to ’1’.

Trap Mode Control Bits 1, 0
These two bits define the behavior of the selected
outputs when leaving the trap state after the trap
condition has become inactive again.
A synchronization to the timer driving the PWM
pattern permits to avoid unintended short pulses
when leaving the trap state. The combination
(TRPM1, TRPM0) leads to:

The trap state is left (return to normal
operation according to TRPM2) when a zero-
match of T12 (while counting up) is detected
(synchronization to T12).
The trap state is left (return to normal
operation according to TRPM2) when a zero-
match of T13 is detected (synchronization to
T13).
reserved
The trap state is left (return to normal
operation according to TRPM2) immediately
without any synchronization to T12 or T13.
