TB-timer CouNTer bits
A Modulo-N (00 to N-1) up-counter. N is the content of TBDAT.
This counter counts up from 00H to N-1. Then, the counter will go back to 00H and the com-
parator will generate a match signal. The counter will not stop after the Match. Thus, the TB-
Timer will generate continuous Match signals with a fixed period. The TB-Timer is an auto-
reload timer.
