Preliminary Specifications REV.B
Specifications in this manual are tentative and subject to change
Timer A
Figure 64:
Timer Ai mode register in event counter mode, single signal
Table 18 shows the Timer specification in event counter mode when processing two-phase signal with timers
A2, A3, and A4.
Figure 65 shows Timer Ai mode register in event counter mode when processing two-phase signal.
Timer Ai mode register
Note 1: In event counter mode, the count source is selected by the event / trigger select bit
(addresses 038216 and 038316).
Note 2: The settings of the corresponding port register and port direction register are invalid.
Note 3: Valid only when counting an external signal.
Note 4: When an L signal is input to the TAiOUT pin, the downcount is activated. When H ,
the upcount is activated. Set the corresponding port direction register to 0 .
