8-Bit Timers (TMRA)
These timers are paired into two modules: TMRA01 and TMRA23. Each module consists of two
channels and can operate in any of the following four operating modes.

In addition, a timer flip-flop and a prescaler are provided for each pair of channels.
register).
operate in the same manner; hence only the operation of TMRA01 is explained here.
The TMP92CH21 features 4 built-in 8-bit timers (TMRA0-TMRA3).
Figure 3.7.1 and Figure 3.7.2 show block diagrams for TMRA01 and TMRA23.
Each channel consists of an 8-bit up counter, an 8-bit comparator and an 8-bit timer register.
The operation mode and timer flip-flops are controlled by a five-byte SFR (special function
Each of the two modules (TMRA01 and TMRA23) can be operated independently. All modules
