8-Bit Timers (TMRA)
TMRAAB, each of which is comprised of two channels. Each module can operate in the following four modes:
•
•
•
•
8-bit comparator and an 8-bit timer register. Each pair of channels also incorporates one prescaler and one
timer flip-flop. Timer operation modes and flip-flops are controlled by five registers.
independently of each other. Because each module functions the same way except for a few differences as
shown in Tables Table 3.9.1 and Table 3.9.2, operation of the TMRA01 only is described here.
Specification
Specification
The TMP1942 contains twelve 8-bit timer channels (TMRA0-TMRAB).
There are six TMRA modules, referred to as TMRA01, TMRA23, TMRA45, TMRA67, TMRA89 and
Figure 3.9.1 shows a block diagram of TMRA01. Each channel consists primarily of an 8-bit up-counter, an
