Disable TX UART on teensy 3.2

[Felipe]

Hey everyone,

I am currently working on a project where I need to use the three Hardware UARTs on the chip for waveform generation as well as Serial data transmission, so I constantly turn on and off the hardware serial at run time by using arduino's method:

Serial1.begin();
Seria1.end();

However, I should be able to have two serial RX.

I know in the 8 bit AVR it is posiblle by clearing or setting a register to enable/disable RX or TX as required.

how could I achieve this on a teensy 3.2 ?

Thanks
Regards
