TCC On:
The torque converter clutch is on when accelerating.

TCC Off:
The torque converter clutch is off when the output shaft senses the output is slower than the input. So when you brake or use engine braking the TCC will turn off

What effects does the brake pedal have on the TCC operations?
The brake pedal will usually cause the TCC to disengage or turn off.
