channels and can operate in any of the following 4 operating modes.
In addition, a timer flip-flop and a prescaler are provided for each pair of channels.
(Special-function registers).
operate in the same manner; hence only the operation of TMRA01 is explained here.
The TMP91C016 features 4 channel (TMRA0 to TMRA3) built-in 8-bit timers.
These timers are paired into 2 modules: TMRA01 and TMRA23. Each module consists of 2
Figure 3.7.1 to 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 5 bytes registers SFRs
Each of the two modules (TMRA01 and TMRA23) can be operated independently. All modules
