Fig. 12.1 shows the TMRC block diagram.
TMRC Block Diagram
TMRC consists of two channels (TBTA and TBTB) with a 32-bit time base timer (TBT), two channels
(CAPx0~1) each with a 32-bit input capture register, and two channels (CMPx0~1) each with a 32-bit
compare register.
TBTA and TBTB operate individually and have the same operational structure. Here we are going to
explain the case of TBTA.
