    Guillermo -

    The TIMERxTCR register TRB bit ALWAYS reads back "0". See the System Control  and Interrupts Reference Guide for your device. The bit description of TRB says - "The TRB bit is always read as zero. Writes of 0 are ignored."

    To check if the action of writing a 1 to TRB actually works, you can check that TIMH:TIM really does get loaded with th evalue in PRDH:PRD and /or PSCH:PSC really does get loaded with the value in TDDRH:TDDR after you write a 1 to TRB.
