In the Teensy manual for register CMPx_MUXCR there is a bit PSTM which means pass throug mode.
What happens with pass throug mode?
 
Sorry, might help if we knew which manual... Or more specific which Teensy?

For example IMXRT1062 manual we have:

which does not have PSTM
 
Sorry, I have not used this sub-system that much.

The only hints I see are:
Code: 
PSTM
Pass Through Mode Enable
This bit is used to enable to MUX pass through mode. Pass through mode is always available but for
some devices this feature must be always disabled due to the lack of package pins.
0 Pass Through Mode is disabled.
1 Pass Through Mode is enabled.

Code: 
For cases where a comparator is used to drive a fault input, for example, for a motorcontrol
module such as FTM, it must be configured to operate in Continuous mode so
that an external fault can immediately pass through the comparator to the target fault
circuitry.
