The trap function switches selectable output lines of the CAPCOM6 to predefined levels
simultaneously. The trap function is triggered by an external signal connected to input
CTRAP. This feature provides a very efficient means of protecting external circuitry,
such as power bridges for inverters or motors, which are connected to the CAPCOM6’s
output lines. Register TRCON enables and controls the trap function, register
CC6MCON or P1L provides the output levels during trap state.

Notes
Reference Point 1):
Input CTRAP is activated,
the outputs
immediately switch to their
trap level.
Reference Point 2):
Input CTRAP is inactive,
the outputs switch to their
programmed level
synchronized to a
new timer period.
Secure Trap State
During trap state the
outputs CC6x and COUT6x
which are selected for T13
modulation are not
modulated with T13’s
output signal but rather
with its initial value.
